Yes I did, but I returned a couple of weeks ago to sign a contract to rent a small condo at Jomtien Beach as a long-term 'base', since I've now retired from in-class teaching. So I wasn't in Mandalay when the earthquake occurred.
However, I have seen the damage etc from friends in Mandalay and at Inle Lake, and so I'm trying to work out a way to return legally to Myanmar to run my charity efforts. Basically, the issue is to get a viable visa, not a short-term tourist visa, and I'm speaking with lawyers in Yangon about that.
