Personally I'm about as interested generally in folk activities in Maine or Queensland as I am in activities in Yorkshire. I'm not likely to get along in either case (leaving aside say Whitby Folk Week), but if the thread is about the ins and outs of how things work, and about how they could work better etc, that's all relevant to me. If it's just about who's on next week, it's not really.

So long as the thread heading indicates that kind of stuff, that's all I ask of it, and I think that can be done easily enough. I see no value in filtering out the threads I am probably not going to open, because I can't see any realistic way of doing that without filtering out threads I would be interested in opening. Still, if people wish to do that, so long as the thread titles contain the necessary information, we already have the facility to do it.
