If I understand correct looking at other threads, it is not possible yet to assign the option of using classifieds for groups only in buddypress?
I was considering to add it to groupblog of a group after subscribers used a paid option with the membership plugin. In context, members who are not able to create groups can sign up free. If you want to create groups together with listings there is a paid subscription.
Am I on a dead end here or does the wpmu dev team know certain options?
Thanks for the feedback
