to making someone a moderator of a tribe that doesnt have a moderator

The moderator of the Etta James Tribe unsub'ed. we have chosen someone to replace the old moderator,but our attempts to go thru the proper protocal to do so is going unanswered. 2 attempts have been made, possibly three actually over last 2 weeks. I have done this myself before and have been made moderator with in a 24 hour period each time. (i have done it like 7 times)

Has something changed in making someone a mod? Do we need to sacrifice someone? I have canidates I wouldnt mine sacrificing.Or is there no one in charge of this particular function at this time?
