I'm still trying to wrap my head around the right solution for my blog/forum combination.
I found this great vBulletin site, Mystery of the zen hex - ZenHex Vortex - Information is Doomed!, which according to Big Boards (Forums Rankings - vBulletin forums, all languages language, website ranking by members) has 2,187,134 posts and 8,556,729.
Love the theme and functionality (color is awful).
BUT - I am desperately trying to stay with WordPress but I understand that vBulletin is not a WP add-on, is this correct?
Does anyone know if vBulletin or any of the other forum software have instant chat, group chat, video chat?
