I'm one of those people who loves to write 24/7, and has become a pretty good editor, so even if I'm working on a story of my own, or reading all of the other great ones out there, I wouldn't mind helping someone out if they needed some editing on grammatical stuff in there stories just to bring them more to life. It's what I love to do, and I'd do it without criticism and help anyone who asked. So, yeah. :) 
Peace out, and write on! :)
