I guess the title should really be "Rule and Regulation," since there are only two, but in any case, they will both be enforced aggressively.
1. Be civil. There will be a zero-tolerance policy for snide comments, condescension, personal attacks, or just generally acting like Paul Ashman. (See what I did there? That's not allowed.) Personal baggage needs to stay out of the comments. If you can't handle that, you shouldn't post.
2. Stay on topic. Any given comment thread should only contain comments about the related article or the particular aspect of L5R that it discusses. Because this blog is about the mechanics of the L5R CCG, that means absolutely no storyline or role-playing discussions, and no posting in-character.
