I would prefer doing mostly grammar, spelling and sentence structure editing. Also, I would rather not work on anything that has Male Homosexuality (not against it, just doesn't feel right when I read it) or anything to do with what naturally comes from the back end of most living things.
Though I am only a student, I have many people at my school come to me for help on the three editorial items listed above.
Note: I can do Spanish Translations, but I am a little rusty when it comes to perfect grammar and spelling. So... You have been warned!
