There is no Moonwell in Ironforge. For starters a moonwell does need to be in view of a moon, and since Ironforge is in a Mountain, no moon, well, no moonwell! :-) That pool in the mystic area is just that, a pool. I have always had to fly my toon to SW to do mooncloth converts ( I hate going to Kalimdor). i think there is also a moonwell in Duskwood in the middle area, green dragon forbidding.
