Not really needed.
As for the idea of administrators being forum moderators, don't even go there. Some topics have in-game administrators in them who blab words to other members, and request the topic to be locked when something is said back (not mentioning any names here). If the in-game moderator requests the lock, do you think they're not going to lock the topic? No, of course not. Like others have said, it is completly different from in-game moderating.
