I think it is a little unfair to comment on the etiquette of sessions in this thread. Especially the informal and ad-hoc gatherings in the food tent!! A reminder to those organising programmed sessions about being inclusive, especially to those faces that are not so familiar, is always usefull, but please acknowlege that it is not an easy task in a regular weekly/monthly session (plenty of threads on that tipic!!) and VERY difficult to get it exactly rite in a busy and bustling festival. "Well done" I say to those who put themselfs forward to organise/lead sessions, those at Beverley that I know personally would, without exception, always do there best to be inclusive, (untill they fall over from beer poisonong that is:-)
