I don't think that is an option Stanley. Checked last night and the site is now reporting two admins, both based in Indonesia! As I can only access with my normal FB profile I cant see any further details. There doesn't seem to be any other changes apart from denied access. From what I have read, a give-away can be a change of the registered email address but that is OK.
Very frustrating, we have events to publicise and the messaging via the site is used by folk who want to contact the group.
