You HAVE to get rid of that little label that follows your screen wherever you scroll to. That is the most annoying thing ever!
I think Geocities tried to force everyone to have those on their pages for a short time but everyone almost rioted.
Seriously, people are already on one of your sites, there's no need to advertise more to them about it, especially in such a way as that.
Beyond that one little detail, everything else looks pretty good. The portal is clean, the forums are well colored and look good. It does take kind of long to load, not sure if you can change that significantly, might find another host if you can.
