1.) Try to be PG-13 above the cut, and only above that when you've warned PG13+, R, or NC-17. 2.) Spoilers should probably be cut, especially come the actual show. 3.) Credit things. Articles/Images/Fanworks/etc. It's just polite. 4.) Don't troll. Don't wank bait. If you say something stupid, and get called out, accept it and move on. Don't ship wank bait either- it wasn't cute for A:TLA and I will bring the wrath of the Avatar state upon you if you try to start unfunny ship wars. Fanon and Canon can coexist.
