In the past, we've had Emperor Cartagia, who in spite of her alias I know is female, and various others using female names who may or may not have really been female. The only current writer whom I know for a fact to be female is ragan, but some of the anonymous writers could be. And it's not impossible that some writers that I've always assumed to be male are in fact female.
I should have mentioned that if you're nervous about what sort of reception you'd get here as a female writer, then I don't think that you need worry on that score. But you could always write anonymously, or using a male or ambiguous handle, if it would make you feel more confident.
Hello Kralia. Welcome to Sir Toby's Extend-A-Story! I hope your stay here is enjoyable.
Unfortunately, it appears that there are not too many female authors here. Or perhaps there are, but they don't speak up. But don't be worried. We're a friendly group of people.
