Subscriptions for Group Members
 

I'm interested in possibly using vBulletin for an umbrella nonprofit organization that wants to support small local nonprofit groups & projects. So, each organization/group would have their own sub-forum with both private and public threads (with different permissions within each group).

Then, I'd like the subscription page to allow users to choose which groups to join/support via an annual subscription payment. Whichever groups they join, they will then have access to those forums (and other group content if we get the complete CMS system).

Is this possible? I see from a forum search that someone else reports when their members submit a 2nd subscription, they get automatically deleted from the first.

Thanks,
Jennifer
