Go to the Options > Discussion panel and make sure that An administrator must approve the comment (regardless of any matches below) is unchecked. With that option selected, all comments are sent to the moderation queue to await approval. Make sure that Hold a comment in the queue if it contains more than x links is not blank and contains a number higher than zero. If this value is blank or zero, all comments containing links will be moderated. If the option mentioned above is unchecked, the link moderation value is higher than zero, and you still have this problem, your Spam Words list probably has blank lines, punctuation marks, or single letters between the information in the list. There should be spaces between the listed items or each item must be on its own line. If you have done this, then upgrade the comment spam plugins you have installed. If this continues to be a problem, deactivate the comment spam plugins one by one to determine the culprit and contact the plugin author for help.
First, unchecked Allow people to post comments on the article on the Options > Discussion panel. This will only disable comments on future posts. Now, to completely disable comments, you will have to edit each past post and uncheck Allow Comments from the Write Post SubPanel. Alternatively, you could run this MySQL query from the command line on a shell account or using phpMyAdmin: UPDATE wp_posts SET comment_status="closed";
If your goal is to permanently disable comments, then you should delete the wp-comments-post.php file as well.
First, unchecked Allow link notifications from other Weblogs (pingbacks and trackbacks.) on the Options > Discussion panel. This will only disable trackbacks and pingbacks on future posts. Now, to completely disable trackbacks and pingbacks, you will have to edit each past post and uncheck Allow Pings from the Write Post SubPanel. Alternatively, run this MySQL query from the command line on a shell account or using PHPMyAdmin: UPDATE wp_posts SET ping_status="closed";
If your goal is to permanently disable trackbacks and pingbacks, then you should delete the wp-trackback.php file as well.
To change your Admin Name, in the Administration Panel, choose the Users->Your Profile tab. Make your changes there. However, you are not able to change the username from within the Administration panel. In order to do this you must directly edit the MySQL database, however this is not recommended as your username is not often seen by other users.
