We just went through this. We stumbled along with the status quo when our CO deleted his account as to change command requires the squad to be deleted and restarted.
When the former CO reactivated his account, the squad killed itself and had to be restarted and everyone reinvited. Some folks might have logged on thinking they had been booted from the squad.
Maybe the best course of action would be some sort of succession planning, i.e. a method for the current squad CO to assume command without killing and restarting.
