I don't see what the point would be to make the "report post" link availabe only to admins and moderators. They're the ones the report would be going to anyway!
To get rid of the report post link, in the
postbit template, find this:
Code:
<p align="right"><smallfont><a href="report.php?s=$session[sessionhash]&postid=$post[postid]">Report this post to a moderator</a> | $post[iplogged]</smallfont></p>
Change it to this:
Code:
<p align="right"><smallfont>$post[iplogged]</smallfont></p>
