I have always liked MyBB since version 1.2.6, but I never pushed phpBB to the side because its very versatile for those who like to really incorporate their forum with their site and blog seamlessly. However if I had the money, I would own Invision Power Board. I have always loved it, always will. I have tried vBulletin, but just hate the user interface.
I like mybb I have vBulletin licence but I am not too keen on it. mainly because I am not too good with the templates. I do like IP.Board mind as it has paypal and built stuff in. now I like mybb but need this one sorting out
