I'm glad that you're dumping phpBB... its horrible programming and it puts a LOT of unneeded stress on the server.
That said, I just hope I can get used to
vB. I absolutely HATE
vB with everything in my being and I'm a diehard SMF fan and use SMF on my own board.
Either way, I'm going to stick around. I'll probably just be annoyed with the forum for a month or so :P
