Well 'dream' (Big Boss) of The Dream Team has not been here since June 2003, yet the fellowship is still there. Most people have left it now, but there are a few left.
Maybe the Members of a fellowship should vote on what should happen.
In dream's case she did state she was leaving, but no one offered to take the Fellowship over and she did not nominate anyone.
So i would say, mark the fellowship is "inactive" until new Big Boss candidate appears, and would have to be appointed by you Fencer.
