Okay, after some thought and prodding by people, I've decided that since the community seems to have stalled at the current number of members and because several people have expressed interest, I'll allow those who want one to take a second character. Before you claim a second one, however, make sure you have the time and will to play both, to avoid things stalling. If you are interested in a second character, just follow the same procedures you did for claiming your first.
Next, I'd like to announce that I've appointed shadowed_past_ as a co-mod, because I'm a lazy git and I often need help in getting things done. So, yay!
