I actually like the red everywhere... A bunch of websites are so into blues and purples that It begins to get boring... keep the red! You could put other colors here and there.. but keep the red!
You need a favicon. Browsers with tabs will be more attracted to the website if it has an eyecatching favicon, and not the standard vbulliten one.
A logo to go with that favicon would help the site alot. even if it's clipart of some cartoon guy yelling... something eyecatching but not tacky, that fits with the theme and design of the site.
You might want to make the administration area into a private forum, as most successful forums do. People often feel uncomfortable if they feel that the site owner is new at this, or struggling... it doesn't breed confidence in the site if new users can see the posts (or lack of) in the administration area.
The General are is lacking the sarcastic titles of the rest of the forums; jazz it up a bit, make it interesting, and not just a forum area to be overlooked. This area needs to fit with the theme of the rest of the site. Maybe the introduction area can have a subtitle like "Oh great.. another n00b who wants to cry about his mean mommy"
Ah, yes, that brings me to another idea...
Everyone has problems with their family. Everyone can relate to problems with family, because everyone (except orphans) has a family. So... you might make a forum to rant about family members. It should be member's only though, for privacy reasons. (no-one wants to google their own name, to find out that thier sister absolutely loathes them!)
