Re: insert a post prior to first post
Would it be the same on the top of every topic, or would you want the ability to post something different on each new topic? If you always want the same thing, you could just edit the template file topic.php and put the content you want displayed there. There is also this function (in 1.0 anyway) in topic.php
<?php do_action('under_title'); ?> – looks like you could hook
under_title with a plugin, but if you just want the same thing at the top of topic.php, I think I would just edit the template file.
