I know there hasn't been much done on this since vBulletin is not opensource, but I think if someone could find a way to do a legitimate bridge with CB, as far as the login procedures go and maybe make a few plugins, the work would definately be appreciated by the CB community. The current vbridge seems pretty buggy as far as CB goes. I could make a monetary donation to this project and I am sure others could also. I know there is perfectly good SMF and PHPBB bridges out there, but users out there are so used to the vBulletin setup. Thanks!
