I agree 100%! Most groups set their own number, but that is something we can consider.I could be completely making this up, but didn't you have to have a certain number of CB posts to access the private groups? I like that idea because I feel much more comfortable with a group of people who regularly post, vs. feeling like there might be a lot of people lurking in the private groups who never share anything.
some had 10 posts. Others had a time - being active/registered for 3 or 6 months. The # of post idea is tricky because people just post simple questions or replies just to hit the limit. I prefered the "active member" for a certain number of months. People could still post their questions to the main forum until they hit the criteria.
