Just a suggestion. Rather than instructing that your code be installed underneath:
PHP Code:
<td class="alt2"><img src="$stylevar[imgdir_statusicon]/$forum[imageprefix]forum_$forum[statusicon].gif" alt="" border="0" /></td>
You might want to say to install above:
PHP Code:
<a href="forumdisplay.php?$session[sessionurl]f=$forum[forumid]"><strong>$forum[title]</strong></a>
I only suggest this because doing it your way created a problem for me because I have a hack installed there already that changes the background color of each forum listing with a mouseover. I installed it a long time ago, and didn't recognize it at first, so it took some playing around to figure out the problem.
Just a thought.
