At High Reaches, we spend a lot of time role-playing, rping for short. It's our major form of interaction, though we welcome and love stories for the zine as well.
Our mailing list is at http://groups.yahoo.com/group/High_Reaches_Weyr_5P/ . We use the same list for everything, from rps to general announcements. This page covers the basics of rping and stories, but the most important thing of all is to have fun and to enjoy ourselves.
