Well, as the Moderator in charge of the Ron/Luna-forum and an avid Ron/Luna-fic-writer, my suggestion is to try and write some yourself. If you're out of ideas, please feel free to look through the challenge-forum for a good idea that you feel like writing. Or, if you have ideas but no time/energy/writingness/e.t.c. then why not issue out some challenges of your own?
I've recently finished one ficlet and am gonna edit another, and then I'll put up some of it here for your viewing pleasure.

Help spread the Red Moon love, fic today!
(All you need to write is a good text or word program and a bit of "Let's do this!". Plot ideas and a cup of tea is also good.
