I stopped looking at and unsubscribed from the How Was Your Gig thread long ago as I don't like endless threads, as that thread is not easily searchable, and all the bands are thrown into it together. If I wanted to look for a certain gig by a certain band, I would have to read the thread backwards without having any idea whether the gig has been posted there and at what point in the sequence. I doubt that thread is a good substitute for what I'm trying to do here.
The subforum solution would undoubtedly be the best, except that it's less immediate than the pinning, and may split the potential readers of the Gigs forum into those who go directly to Band Media Stuff or whatever we'd call it, and those who click on Gig List instead and don't bother with the other subforum.
Not an easy one, I know. The pinning solution would be best for keeping readers together IMO, but definitely not if there are like 20 pinned band threads before we can even begin to see the gig list.
