Participate in Role Play Writing Stories

Looking for a creative writer to help plan and write science fiction stories and novels. These will be done in a role play writing format in instant messenger so I need someone with great availability during evenings and weekends. I am in Chicago time zone so consider that when applying. Looking for someone with no limitations as these are sci-fi/drama, and sometimes mature. Must be able to write about things such as science, human anatomy, bodily fluids, language, violence, and nudity.
