Dem catgirls. Yessss!
Star Army's got a big setting but a simple concept, which is just writing stories with each other, and I think you should be fine. I'm Wes, the site's founder and webmaster guy. I run the main faction of the site, Yamatai (home of the Nekovalkyrja, our mass-produced catgirl soldier race) and have an RP called the YSS Eucharis. Besides those I do a lot of work behind the scenes, working on the site and promoting it. I'm glad you're interested and I want to help you get involved, so feel free to send me as many questions as you want.
