Flaming/Flame Wars
Flaming is reacting to someone's board posting or PM in a hostile manner by publicly chastising the person or bombarding the person with nasty posts or PM's. Flaming may occur to users that engage in behavior that violates what is considered proper board netiquette. A flame war occurs when two or more users flame each other in an escalating manner that threatens to continue unabated. If you notice a flame war developing just notify the moderator or adminitrator and let them handle it. Do not take part in flame wars. If you do you will be banned even if you did not start it :-)
UPDATE: they sent me another letter yesterday, pretty much the same letter with the cover page done by someone else and I noticed they actually sign it with a pen, not a copy.
I was reading the federal mumbo jumbo included and basically it says according to federal law they must post this for 3 consecutive weeks before they can legally make the shipment property of the US gov.
