Let's see...what to say:)
I'm a 30-something Sam/Jack shipper, adore angst(but only in so far as it makes a happy ending sweeter), and will never write character death(er...permenant, anyways), rapefic, or babyfic. (Baby Tok'ra don't count). Which is not to say that I don't respect writers capable of doing so...I do. But I won't write it.
I adore reading stories with a seminar/training basis, transformation stories (physical that is) and stories that have SG-1 intersecting with the real world a la Seth and the reactions of the outside world to them.
