I read the description of the plugin for vBulletin, but I'm not quite clear about it. We have a vBulletin system installed, with existing users. Our goal would be to create some closed forums that would only be available to members, in addition to our members only content in other parts of our site. Do we need to have every vBulletin member reregister with aMember? Do we manually add vB members to aM if they become paid members, and leave the unpaid members alone in vBulletin? Do we need to completely jettison the vB membership data and move everything to aM? If so, how do we do it? A data dump and import?
