I am a fairly sarcastic, semi-grammar nazi, who has beta'd regularly for three or four people in the past. I took a break from it for a few years while working full time and then staying home with my youngest child. She is going to be starting preschool in the next few weeks and I am hoping to find someone to beta for in order to have something productive to do while she is gone for four hours a day. I enjoy any level of involvement with a story, from simple spell checking, to untangling grammatical knots, to helping with suggestions if you are stuck on a story line. I don't tend to shy away from most subjects, but I prefer not to beta anything with violent/graphic rape unless it is really, truly necessary for the story arc. I'm absolutely fine with any and all slash/threesomes/moresomes, BDSM, etc.
In the past, I have beta'd for Smallville, BtVS, Gensomaden Saiyuki, and a few original stories. I'd be happy to beta for any of these, and I'm also very (ridiculously) familiar with several other canons, especially Harry Potter, Doctor Who, Vampire Diaries, and Lord of the Rings. If I'm not familiar with your topic, I don't mind doing a little research to familiarize myself with it if necessary. I had never actually watched Gensomaden Saiyuki before I was asked to beta for someone who was writing about it, and I ended up enjoying "catching up" on the show. I am willing to work on just about anything, so please don't hesitate to ask.
I hope to hear from someone soon!
