We're not quite as strict about some of these as this post from a long time ago suggests -- usually we just delete any offending comments -- but it's sometimes useful to post a refresher because of our growing traffic and because it's easy to forget. Most of it's common sense: Don't attack other members and don't make fun of other people's faith or politics or ethnicity. Just had to delete a couple of comments and issue a warning over the last couple of days, so I want to make sure that we're all on the same page.
