I was looking through some old posts in one of my linkedin groups and I saw one where the question was asked as to whether or not the groups should keep accepting new members. The premise was that the group was big (10,000+ members) and they were accepting 30 new members per day. The suggestion was that membership could only be maintained by each member by continually participating in discussions. Understandably, some newer members were concerned that they would be cut out of the group.
Is it ever right to limit membership totals to an online community like Linkedin groups or even DaniWeb Forums? And if so, how easy would it be to setup membership requirements for groups where there may be broad interest and large numbers of qualified potential members?
