It does on the Welcome Message, and you're logged in and can't see it.. I just told you the wrong template.
Do the tcat > tcat2 replacement for the
forumhome_forumbit_level1_nopost and
forumhome_forumbit_level1_nopost templates.
It looks like you have the tcat in
forumdisplay set up to have an image, too... so you'll need to do the same thing there. Look for the <td class="tcat" .... > around the phrases "$vbphrase[threads_in_forum]" and "$vbphrase[subforums]" and replace it with tcat2.
--------------
Oh, well it looks like all your "tcat" classes have a large left padding.. If you're not going to be putting an image in "tcat" you should get rid of the "padding-left:100px" out of the CSS rules.
Here's a shot of the only place where it's actually working, in case you don't believe me..
