In relation to one moderator -
I agree with what Karolina says about terms - she suggested 4-6 months, I'd actually thought that we could have one or two month terms, then the group could decide if they want that moderator to continue or not (this is not to say that they couldn't be voted out before then if people feel they're not right in some way).

More ideas ... we could take turns. Like, the first person creates the account, and then when it's time for a new moderator, they can pass on the account details ... the new mod could change the details if they wanted.

Daisy, you raised the issue of someone changing the account information, refusing to leave, - yes, well we did just have that .... I hope that if someone hasn't got the integrity to leave when asked, that the example of how we were able to get help with that would deter creating such another situation.

More about taking turns ... maybe if we all had turns for say a month or so, some of the huge feelings many of us have around the moderator thing would lose it's power? whether we are or whether we aren't?
I'd like to experience it, whether it's me or someone else, as a benign caretaker position.
That's how I felt when Nomad was moderator.
Maybe if we took turns, in this way, it may help build trust between us?

Maybe we could build up to a council? placing in it people who have moderated with integrity and have built up trust?
