Well, if the site is going down, we ought to figure it out before it does and people disappear.
Lance, if you're sick of dealing with the site (kinda sounds like you are), turn over the administration to someone else who is willing to put in the time. And if I misread your attitude, I apologize.
Either way, here's my idea. Figure out what it will cost to keep the site up for say, another 3 months. Put one of those running costs banners in all the forums and see if people actually ante up for the three months. If they do, you/we've got three months to get things figured out further. If they don't- people obviously don't care and let it go with clear conscience.
Question: how much time does the site actually have in it's current home?
