There's the Forge which is a SQL testbed/semi serious server, plus other servers coming.
I think although the forums are quieter than they used to be, there's a lot of lurkers (myself included, my work means I'm gone away a fair bit but I still check here) judging by the Currently Online listing I usually see when I log in...
I'd say keep tuned. Age notwithstanding, this game is far from dead.
