###Comment as answer
**This is not a forum. Please only use the 'Post Your Answer' button if you can answer the asker's question; [post a comment](http://$SITEURL$/privileges/comment) otherwise.** We require some [reputation](http://$SITEURL$/faq#reputation) before you can comment others' posts to prevent abuse; why don't you try and get some by [answering a question?](http://$SITEURL$/unanswered)

###Question as answer
**This is not a forum. If you have a different question from the asker's, please use the [Ask Question](http://$SITEURL$/questions/ask) button** instead. You don't even have to login!

###Upvote as Answer
**This is not a forum. If you wish to thank somebody, you should [vote him up](http://$SITEURL$/privileges/vote-up).** We require a little bit of [reputation](http://$SITEURL$/faq#reputation) before you can do that to prevent abuse; why don't you get some by [answering a question?](http://$SITEURL$/unanswered)

###Show you made an effort
What did you try? What didn't work? What should have worked? What didn't you understand? What did you understand?

###Nothing but a URL (and isn't spam)
Whilst this may theoretically answer the question, [it would be preferable](http://meta.stackoverflow.com/q/8259) to include the essential parts of the answer here, and provide the link for reference.

###Requests to OP for further information
This is really a comment, not an answer. With a bit more rep, [you will be able to post comments](http://$SITEURL$/privileges/comment). For the moment I've added the comment for you, and I'm flagging this post for deletion.

###OP using an answer for further information
Please use the *Post answer* button only for actual answers. You should modify your original question to add additional information.

###Work on your accept rate!
Improving your [accept rate](http://$SITEURL$/faq#howtoask), will make people more inclined to answer your questions.

###Use code formatting
To format code put four spaces before each line, or select it and press the `{}` button in the editor. For more formatting help, please refer to the [Markdown editing help](http://$SITEURL$/editing-help) page.

###We won't do your homework
Most of us here are professional programmers. If you ever make it through your studies (with that attitude), you are quite likely to end up as the fellow-worker of a SO user. So we better not help you avoiding to learn something until then.
