in forum proceedings. There's often no apparent reason, but it happens, and has been happening for years. Perhaps there's a shortage of real news, or interesting topics - whatever.
When it happens please resist the temptation to post those "I'm bored - what are you doing today?" threads. That's the stuff of innumerable chatrooms, and it's not what we're here for. Please try to ensure that when you start a new thread it has a point - one that might appeal to others, and start a discussion.
