The chat room, indeed, dozes dormantly like a TV that is turned off & the only thing necessary to turn it on is for one member to enter.
It probably doesn't occur to people that you can use it as an impromptu discussion room with just one other friend if you want to, say, hammer out a rally meetup time. I've done that often.
I've been thinking of setting a late-night chat for fellow insomniacs whom I see regularly on the forum at 2 a.m. (you know who you are!).
Of course I'm an elitist. Look around you.
