To change your settings just click your profile and click Blocker Settings on the left.<br/> To block a user just open their profile and click "Block" on the top right corner of their profile. Alternatively you can do this through the settings by clicking Add and entering their name into the dialog box.<br/>In Blocker Settings you can unblock a user or topic by simply pressing \'remove\'. You can also unblock a user by going to their profile and clicking Unblock on the top right corner of their profile.<br/>In the settings a blocked user will have three checkboxes. The first one allows you to decide whethe to block their posts, second quotes, third topics, and fourth whether to show the reveal post button.<br/>If you have any questions then feel free to <a href="https://forum.blockland.us/index.php?action=pm;sa=send;u=132993">send me a PM</a>.<br/><br/><input type="button" id="dismissInfo" value="Gotcha"/>';
