Social Groups Forum Groups (Groups dedicated to a forum)
 

Social groups usually gather a group of people with similar interest. In many cases the topic is already centralized in a (sub-)forum. So there is not much use in having discussing the same topic in the group.
At the same time, it can be mighty handy to have a group dedicated to a specific (sub-)forum, so that you can easily see which members have interest in the forum.

So please add functionality to replace the group discussion by a (sub-)forum. So that the group is connected to the (sub-)forum in question.
