From the group managers forum:
"I administer group for organization. It is for member only. It often happens that someone looses member status and we want to stop that persons group membership. But, we do not want to remove user form the group or ban him.
We just want some kind of temporary disabling his group membership as usually organization membership is regained and user has to be activated in the group again.
Is something like this possible or I have to file feature request?"
This has been asked by several forum owners/moderators. Any possibility that this may be a coming modification?
