Thread:"public" "private" "open groups" "closed groups" (2)

I am of the opinion that closed groups are required for creating quality content. While creating any content the author must have certain ideas and he/she may need some time for implementing his ideas interacting with some limited individuals who are part of the group. The content may be kept open only after this completion. Once it is open then anyone can edit. We may keep some time frame for such closed activity.
