Okay, to remove the words Sub-Forums: is a two step process.
Admin CP > Languages & Phrases > Search in Phrases
Type in
Sub-Forums and click Find. Scroll to the bottom until you see the GLOBAL Phrases Containing 'Sub-Forums' section, under it you will see
subforums Click on the Edit button. In the box hit your space bar one time to leave a space or it will not overwrite the current phrase.
Edit your forumdiplay template, find:
PHP Code:
<td class="tcat" width="100%">$vbphrase[subforums]<span class="normal">: $foruminfo[title]</span></td>
and remove the colon so it looks like this: (right after normal)
PHP Code:
<td class="tcat" width="100%">$vbphrase[subforums]<span class="normal"> $foruminfo[title]</span></td>
Granted, this method is just a quick slap together but it will remove your sub-forums text from your forumhome
