Mine is a paid one-on-one support forum and I am trying to find a way that different user groups can be allowed to post different numbers of questions per month according to how much they pay each month. At the moment it is a free for all, and a small but persistent number of users are abusing the service.
So if user A has Gold membership he can start x threads per month in forum A
User B has Bronze membership and can start y threads per month in forum B
Is this possible or is there an add-on for this?
