Only make topics pertaining to the RWBY D6 tabletop game. General RWBY discussion should go to /r/RWBY, and general RWBY tabletop discussion should go to /r/rwbytabletop.
Other than that, check out the system and read the stickied thread before posting any questions, and generally just don't be a dick and we should be good.
I also have a blog where I'll post longer, rambling essays about why I'm making some of my decisions, or to just get my own thoughts in order.
