Here is a fun website that diagnoses whether you write like a boy or a girl.
I was pretty happy because when I posted my stuff from a guy's point of view it said I was a guy, and my girl P.O.V. was overwhelmingly girl. So maybe I'm on the write track? When it was stuff that involved both boy and girl characters pretty evenly it said I was a girl, but sometimes it was pretty close!
It's a lot of fun, check it out!
