I joined Ning, a social networking site, a year ago and had no idea what to do there. Fortunately, P.O.W.E.R. (Promoting: Ownership, Writing & drawing, Editing and Reading) came along. I joined immediately upon seeing a blog post about it (so quickly, I forgot to make note of where I saw it mentioned). It's about networking to find ways to promote those good concepts in the parentheses for women and minorities in comics. If that's something you agree with, join. Now. You'll be glad you did.
I added a link to P.O.W.E.R, hereafter to be referred to simply as POWER, in the sidebar.
