Once you've joined, you can discuss anything you want about the comic -- the plot, the characters, the art, whatever! It can be something you like, something you dislike, or merely something you found interesting. Whatever you want -- so long as it's RM related. All we ask is that you put spoilers (See: anything major after Chapter 8, Book I) under a LJ cut, and that you be respectful to the other members.
Seeing as this community was just put up and I've yet to announce it, kudos if you found it. XD; Seriously, join and get this place moving!
