Lil' Psycho: You don't have to teach TMs in the Training Centre, zones are okay, it's just that if you're a member for a few years and can't remember where you taught a move to a Pokémon (people used to post in zones, random shops, TO on various boards, giveaway threads, etc.), then it's easier to have one specific shop as a reference point so that's where the Training Centre comes in.
