1) You've all had English classes at least once in your life. Use them.
2) If somebody is gay, that means he or she is homosexual. It has nothing to do with that person either shooting you or just having shot you.
3) There's no "a" in "ever".
4) Lol means "Laughing out loud". Typing "lol" at the end of your own (decidedly unfunny) joke means you laugh out loud at your own jokes, which mostly means you're a moron.
5) Rofl means "Rolling over the floor laughing". If you can type while rolling over the floor laughing, make sure to tape that and put it on Youtube. If you can't, don't pretend you do.
6) No matter what you think, there is no "best game" out there.
7) "Freedom of speech" exists, but you are not the only person on this planet, and most certainly not the most important. Words have power, and a simple remark can hurt people. Use that power responsibly.
8) If you're uncertain whether or not you should say something, don't say it at all.
9) Gaming is supposed to be fun. If it's not, go find another game.
10) Being a "newb" or "noob" has nothing to do with experience, it's a state of mind.
11) Graphics age, design and animations stay. It's not in the amount of polygons or how many bits go in the texture, it's about how they're used. That's why Another World [http://en.wikipedia.org/wiki/Another_World_(video_game)] is still looking good.
12) Friendly competition can be good, but don't overdo it.
