Ye' old general discussion board. Basically, for everything that isn't covered elsewhere. Come here to shoot the breeze, shoot your mouth off, or whatever suits your fancy. This forum is not for asking programming related questions.
Once again, phpBB is the one we used, for many reasons. Also, Invision Boards wasn't out when we launched with phpBB, so it wasn't an option. And phpBB has all the features we need. So the real question for me is do I want to switch boards and have to reimplement the features I enjoy, or just continue to use something that works?
Vicious: I disagree. I have a very active user community that uses the phpBB forum system, and it works very well for our needs. If it sucks ass, that must be a good thing to you then.
