Both real and somewhat funny. I am at work and have a lot of time on my hands

#1 don't: to online gaming. NEVER EVER give up the keys to your account to anyone PERIOD.
#2 don't: Don't Cyber. Its a proven fact that 80% of females in online games are not Females. LPN and a few others are few and far between and they don't ever cyber.
#3 don't: Don't give out your real ISP e-mail to anyone who is not a long time trusted friend. Get a free online account on yahoo, or hotmail for online gaming communications.
#4 don't: Don't ever sacrifice real life for a game. These things can be addictive. Have fun, don't get crazy.
#5 don't: If you are about to put your fist through the monitor. It's time to turn off the PC and do something else. PC's ain't cheap and the fool that ticked you off will only laugh once he/she finds out what you did.
#1 Do: Have Fun. Online gaming is a blast. Just remember its Fun damn it!
#2 Do: Make friends, but be mindful that there are a lot of creeps in the world and you can't see the folks on the other end of the keyboard.
#3 Do: Pay your bills on time. Most online gaming companies (about 80%) are flying by a wing and a prayer. If your not living up to your end of the bargain then it makes it hard on the folks that are making your life fun. If you don't believe me then I suggest you do a little math. Think about the time involved in creating and administrating a game like this. Then times the amount of users by 15 bucks a month. The hard ware and software for this stuff plus health care and a decent living subtracted from your total and there are your profits. It ain't much.
#4 Do: Try to attend conventions when ever possible. It's a great way to meet the folks on the other end of the Keyboard in a controlled environment. You will see the reasons for some of the don'ts as well as make life long friends.
#5 Do: Keep an open mind. Folks in online gaming are from every walk of life across the globe and from every price and social bracket that you can conceive of. Online gaming and other social online activities truly brings the world closer.
