How much active the board is? Unless the board is huge active and generating a lot of spam, I don't think theymos is going to add a moderator for that board.
And you also know what rules of considering yourself as a moderator, to report more and more. I'm sure you did that.
I have noticed that my sub-board's moderator is inactive (
mitzie) nearly two months now.
Two months? It will be hard to convince theymos for this I think.
Good luck with your application.
