Just caught up on all the emails and info about UK regulation - my goodness, what a tiring issue to be worrying about.
My sense is to re-invent AT and sell that. Who needs to be an "Alexander Technique teacher" anyway? It's not like it's a fabulously well known brand folks - don't kid yourselves. There's some gravitas to be sure, but you wouldn't lose that anyway: "Based on F. M. Alexander's discoveries but the Alexander Technique NOT."
