This is heartening!
It is so helpful to hear from all of you! Here I felt I was staring the end of my gaming time in the face, and I learn that actually I'm a relative newbie!
The recruitment resources are also amazingly helpful! Part of what has set off this particular concern for me is the recent exodus of several members of what has been a stable gaming group for the past seven years. Folks are just getting involved in their careers and families and moving away. Will post on those boards when I get a chance.
The scheduling issue that many mention is definitely a big factor too. I'm a graduate student, so my scheduling problems are pretty, well, quixotic. I'll have months at a time with a lot of free space, then all of a sudden have to go into a cave for three or four weeks. Does a game keep up the same intensity when so much time passes between sessions? One thing we've been doing is in-character e-mailing back and forth during a long hiatus, just to stay in tune with each other. Any other suggestsions? I'm going to India for six weeks this summer, so I'll be able to put your ideas to immediate use.
In terms of openness, it's kind of hit or miss in academia. Some folks will think it's the most interesting thing in the world, and talk for hours about new perspectives on narrative and social processes and blah blah blah. Actually, no one has done that yet, but I would if I was in their position .

I think it would make a good research topic, actually, but it's not my area. Perhaps I will try the indirect methods suggested. I was thinking an LOTR t-shirt, or something like that. No one goes to my office but undergraduates who, while they may be great gamers, are also my students, and that would just be awkward.
Oh, and that link to the thread on creepy gamers -- that was great! We've had a fair stream of those ourselves, though I don't doubt that we've been pegged as the wierdos one or two times ourselves!
--To the fella who researches religion: my field is religious studies. Lemme know if you ever want suggestions on good reading, especially about South Asian traditions!
