For the record it's the non-music-related threads started by GUESTS that I try to avoid. That means I may miss out on some interesting threads started by interesting and agreeable people who happen to be GUESTS (normally with handles to their GUESThood)- but too many of those threads turn out bad.

"I play and sing at the various sessions and help to organise local music events." That's music related. And as a guest to Stony Stratford I felt it was good manners to respond to a concern raised by someone who had evidently helped to give me an enjoyable weekend.
