May I may give you my honest opinion? Seems to me that this "diplomat" just wants to be in charge. And I think that he is pushing you (He made barely 10 posts!! and already starts asking!). If I were you I wouldn't trust him. If you want to give him a chance, I would say that he first should "earn" his place at your forum by making good contributions. Then if you're happy with it, ask him for the skins he has to offer. Make him a moderator or something but not an admin right away. I hope I've helped you.
