I use vbulletin, but purchased my licenses before the jelsoft takeover, and hate the new license terms by the new owners, daylight robbery trying to get current license owners to upgrade for a crazy amount, I will not be upgrading, I'd rather spend for an IPB license, they got a load of new customers when VB done a Dick Turpin on us, and IPB is probably a superior software anyway. I'm still using my old versions of vbulletin, can't really fault it, it is a good product.
