I have no idea why I haven't posted in this thread earlier. Better late than never, though.
I'm female, I DM, and my current players consist of 3 women and 4 men. I'd love it if one of them would consider running a game so I could play sometimes, but alas, I don't see it on the horizon.
I've only been playing since about a month after 3e came out. I had harbored a secret desire to play since the 1970s, but the only people I ever met who played scared the bejeezus out of me. I had no idea where to find other interested people, or buy the books, or anything like that. I started out by playing online with a bunch of nice, normal people, and although it was a great deal of fun, I couldn't continue in that game because everyone else wanted to post during work, and I don't have time to do that. (Am I the only person in the US who actually has 40 hours of work to do each week? It sure seems like it.)
I have both played in and run online games, and I'm on my second tabletop campaign now. For a while I was playing online in alsih2o's Tuesday night online game, but I had to stop because real life got in the way. It's too bad, because I really enjoyed the game. I hope it's still going strong, and if any of you are lucky enough to get invited to play in his game, I advise you to take him up on it.
