I run phpBB 2.0.8 right now, I like the hacks for it, I HATE THEMES! If I want to add a new theme I gotta edit the hell out of files, a pain in the butt. I am anxiously awaiting phpBB 2.2 to come out. But I have recently started to think about vB as a solution.
for "styles" if I install new styles do I got gotta edit a buncha crap?
also, my phpBB is less fourm based, and more user profile based. I have the fourms, but it's more of a hummm... dating'ish site. I know from word of mouth vB has tons of hacks. As does phpBB. But 98% of the phpBB hacks I tried (and I tried a lot) didn't do much to really make the board stand out from just a "fourm"
if I wanted to build a user interaction site that revolves around people looking at other peopels profiles, and having pictures and galleries and all that good stuff. Would vB be a good option? having 1200 hacks doesn't mean much if none of them will do what I'm after
