First, "If you can't say something nice, don't say anything at all". If you must say something un-nice about a thread (yes, I made that word up) tell it to a moderator. Second, from the English standard bible - "So whatever you wish that others would do to you, do also to them" Third, from the wiccan rede (paraphrased) - "Pay attention to the threefold law. Whatever you do, good or bad, comes back to you three times." Seems simple enough to me.
