That's certainly an idea. There's converters and such in place between SMF and VB that the switch should be pretty painless.
I know everyone's used to VB, but I didn't have the cash to shell out for it year after year, and of the free boards, SMF is pretty good.
I'm trying to come up with an advertising model that'll bring in some cash for the front page, but if you want to do the paypal thing, that'll work for me.
