I am creating a support forum where users cannot see each others' threads. Admins and Modscan see all threads. No problem default XF. What I want additionally is to have very small workgroups, usually partners, but could be up to 6 members. These workgroups can all see each others threads on this support forum. I do NOT want lots and lots of tiny usergroups of 2 - 6 members to manage! There would be a lead user in each workgroup. So what I want is to link the other users on this workgroup to the lead user - so all linked users can see each others' threads. Anyone fancy doing this (paid) or tips on how to wangle it?
