If you mean your account password, go to Blizzard's website, go into account management and select Change your password. The account management page can also be accessed by first opening the game and on the title scree where it asks you to log in go to the bottom left hand corner and click "Account Management.
There you can change anything that you want including your password. You can even get a World of War Craft Master Card that will give you a free month of play. You will even get points so you can get more free months.
Have fun playing, coming soon the big earth quake that will change the whole game and add 3000 new quest.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
