Well, the new forums are up. The upgrade from phpBB 2.0.11 to vBulletin 3.5.4 took about 2 hours. Things look pretty ok, but please check for bugs. I noticed some of the user avatars weren't imported well, so i figure other issues might appear.
The forum looks pretty raw right now, but untill i'll have the time to create a better skin we'll stick to this one.
Feedback is appreciated
