<h2><?php _e('Instructions') ?></h2>
<p><strong>1. What this plugin does</strong></p>
It shows excerpts of the latest comments and/or trackbacks in your sidebar. You
have comprehensive control about their appearance. This ranges from the number
of comments, the length of the excerpts up to the html layout. You can let the
plugin order the comments by the corresponding post, or simply order them by
date. The plugin can (optionally) separate the trackbacks/pingbacks from the
comments. It can ignore comments to certain categories, and it offers support
for gravatars. It only gives extra work to the database, when actually a new
comment arrived. And you can filter out unwanted pingbacks, which originate
from your own blog. And it is a widget.

<p><strong>2. Installation</strong></p>
Since you are reading this text, you already uploaded and activated the plugin.
Now you want to add the plugin to your theme. There are two options to do this:

<p><strong>2.1 Modern Theme with widget support</strong></p>
The plugin is a <a href="http://automattic.com/code/widgets/">widget</a>. If
your theme supports widgets, and you have installed the widget plugin, adding
the plugin to the sidebar is easy: Go to the <a href="themes.php">presentation menu</a> and drag
and drop the widget into the sidebar. Don't forget the Get Recent Trackbacks
box. And you might want to change the title. All done.

<p><strong>2.2 Old school theme without widget support</strong></p>

<p>
You need to insert the following code snippet into the <a href="theme-editor.php">sidebar template</a>.
</p>

<p><strong>3. Customizing</strong></p>
The strongest feature of the plugin is that you can change the html layout in the admin interface, by filling in templates. In the templates you make use of macros, that are later replaced by the actual data.

<p><strong>3.1 Using the Macros</strong></p>
<table>
<tr><td valign="top" nowrap>%comment_excerpt</td><td>The text of the comment. It might get shorted to the number of characters you entered in <em>"Long comments are chopped off at..."</em></td></tr>
<tr><td valign="top" nowrap>%comment_link</td><td>The URL to the cited comment.</td></tr>
<tr><td valign="top" nowrap>%comment_author</td><td>The name, the commenter entered in the comment form. If she left the field empty, the name is "Anonymous".</td></tr>
<tr><td valign="top" nowrap>%comment_date</td><td>The date, when the comment was posted in the style you configured as <a href="options-general.php">default date format</a>.</td></tr>
<tr><td valign="top" nowrap>%comment_time</td><td>The time, when the comment was posted</td></tr>
<tr><td valign="top" nowrap>%time_since</td><td>Time since the comment was posted. For example: &quot;9 hours 16 minutes&quot;.</td></tr>
<tr><td valign="top" nowrap>%comment_type</td><td>&quot;Comment&quot;, &quot;Trackback&quot; or &quot;Pingback&quot;.</td></tr>
<tr><td valign="top" nowrap>%gravatar</td><td>This macro becomes a complete image tag. If the comment author registered a gravatar with <a href="http://www.gravatar.com">gravatar.com</a>. Example:<br />&lt;img src=&quot;http://www.gravatar.com/avatar.php?gravatar_id=1ebbd34d4e45cac&amp;size=25&amp;rating=X&quot;/&gt;  </td></tr>
<tr><td valign="top" nowrap>%gravatar_url</td><td>This macro becomes only the URL to the gravatar. Example:<br />http://www.gravatar.com/avatar.php?gravatar_id=1ebbd34d4e45cac&amp;size=25&amp;rating=X</td></tr>
<tr><td valign="top" nowrap>%profile_picture</td><td>Becomes to URL of a profile picture. Use it like this: &lt;img src="%profile_picture" width=16 height=16&gt;. This only works after activation of <a href="http://geekgrl.net">Hannah Gray's</a> <a href="http://geekgrl.net/2007/01/02/profile-pics-plugin-release/">Profile Pics Plugin</a>.</td></tr>
<tr><td valign="top" nowrap>%userid</td><td>If the comment author is registered with your wordpress, and was logged in, when she wrote the comment this is replaced with the user id, she has in WordPress. The user id's are listed here: <a href="users.php">users.php</a>. You can do fancyful things with this macro. For example you may construct an image url, that points to pictures of all the authors of your blog: &lt;img src=&quot;/images/user%userid.jpg&quot;&gt;</td></tr>
<tr><td valign="top" nowrap>%author_url</td><td>The URL, the comment author left in the comment form, or if the comment is a trackback, the URL of the site that issued the trackback.</td></tr>
<tr><td valign="top" nowrap>%author_url_href</td><td>The same like %author_url but inside a href statement. If there is no URL, the whole macro is empty. Without a href="" statement the link looks like a link, but is inactive. Use it like this: &lt;a %author_url_href title="%comment_date"&gt;comment_author&lt;/a&gt;</td></tr>
<tr><td valign="top" nowrap>%post_title</td><td>The title of the posting that was commented.</td></tr>
<tr><td valign="top" nowrap>%post_link</td><td>The URL of the posting that was commented.</td></tr>
<tr><td valign="top" nowrap>%post_date</td><td>The date when the commented posting was published.</td></tr>
<tr><td valign="top" nowrap>%post_counter</td><td>The number of comments this post has..</td></tr>
<tr><td valign="top" nowrap>%trackback_title</td><td>Only applicable in trackbacks: The title of the trackback. It  might get shorted to the number of characters you entered in <em>"Long trackbacks are chopped off at..."</em></td></tr>
</table>

<p><strong>3.2 Group by comments</strong></p>

If you want to order the comments by their posting, you will have not one but
three templates. The middle one is just the same as in the normal order. The
first and the last template are used to generate headers for the grouped
comments. Usually you will show the %post_title in this header. This is the
html markup that is generated by the templates:

<style type="text/css">
<!--
.top-example { vertical-align:top; }
.top-ital { vertical-align:top; font-style:italic; padding-left: 10px; }
#example { font-family:monospace;
           font-weight:bold;
           border: 1px solid;
           border-color: #ccc;
           margin: 15px;
           background: #eee;
}
#example pre {
    margin: 0;
}
#example td {

}
-->
</style>
<div id="example">
<table style="border-spacing:0px; ">
<tr>
<td class="top-example"><pre><span style="color:green">&lt;li&gt;&lt;h2&gt;Recent Comments:&lt;/h2&gt;
   &lt;ul&gt;</pre></span></td>
<td class="top-ital"><span style="color:green">Start sequence.</span> Automatically provided when the plugin is used as widget. Otherwise you have to enter this by manually into the <a href="theme-editor.php">sidebar.php template</a>.</td>
</tr>
<tr>
<td class="top-example"><pre>
      <span style="color:blue">&lt;li&gt;Post 1&lt;/li&gt;
         &lt;ul&gt;
</pre></span></td>
<td class="top-ital"><span style="color:blue">Template for the post. This is the header for a list of comments, that all belong to the same posting.</span></td>
</tr>
<tr>
<td class="top-example"><pre>
            <span style="color:olive">&lt;li&gt;Comment1 to Post1&lt;/li&gt;
            &lt;li&gt;Comment2 to Post1&lt;/li&gt;
</pre></span></td>
<td class="top-ital"><span style="color:olive">Template for the comments<br />It is repeated for every single comment</span></td>

</div>


<p><strong>4. Miscellaneous</strong></p>
<ul>
<li>Don't worry if you screwed up the template, reset the template to default and try again.</li>
<li><em>"Wrap long words at..."</em> means: words, that exceed this length are split into fragments to prevent damage to the layout of your blog.</li>
<li>"<em>Ignore trackbacks originating from this ip address</em>" on the
configuration page for recent trackbacks is useful for filtering out pingbacks
that occur when you have a link to your own site in a post.</li>
<li>If you select to exclude comments made by blog authors (your own comments) from  the list, then the comments which you made, when you were logged in, are ignored. If you also want to exclude comments you made, when you were not logged in, you can select to also consider the username and e-mail address.</li>
</ul>
<p><strong>5. Interoperation with other plugins</strong></p>
<ul>
<li>If <a href="http://geekgrl.net">Hannah Gray's</a> <a href="http://geekgrl.net/2007/01/02/profile-pics-plugin-release/
">Profile Pics Plugin</a> is present, you may use to macro <em>%profile_picture</em> to obtain an URL to the profile picture of the commentator (read in the macro section for a working example).</li>
<li>If <a href="http://fredfred.net/skriker/index.php/polyglot">malyfred's</a> <a href="http://fredfred.net/skriker/index.php/polyglot">Polyglot</a> Plugin is present, additional filters are applied to comments, titles, dates and times, which select the right language for the user.</li>
</ul>
