No one thought you'd stick with that "promise", Joseph.No Isabella this is neither the right approach nor fair.
Once an election is underway, folks cannot really "resign". The election must continue under the same election law with the same ballot even if folks "announce resignation", in fact there is no such thing as announcing resignation once your name is on the ballot and the voting started. The normal and fair course of action is to allow the election to continue anyway no matter who "resigns". If someone who had resigned actually wins, then they would have won and resigned, and therefore if @Jo wants to replace them, he will hold another election to fill the resigned moderator seat.
I think this is what the next steps should be.
You made me temporarily break my promise of solidarity with @The_FPMer but this had to be said, and clearly.
