A few years ago, a friendly Canadian guy started a teacher's group that would meet on the weekend in Taipei to discuss English teaching (games, activities, methods, techniques). You can read about it here:
Personally, I'd be open to attending something a bit less formal than your average ELT conference, with an emphasis on the practical side of teaching (activities, classroom management tips, etc.). It might be fun to try it with a Pecha Kuchaapproach (where presenters are limited to 20 Powerpoint slides and 20 seconds per slide) or Open Space approach (where participants set the topics for discussion when they arrive). Any other ideas?
