i wanna know how to log in? becoz everytime i try to log in i can't!!! By theway i already have password.

Problems with login are usually caused by a wrong username and/or password. Make sure you have capslock turned off and that you use the right case, both passord and username are case-sensitive!
Older browsers may cause a problem, please let us know what browser and version you are using.
Another thing you can try is to delete the cookies on your computer, and try again.
If you think your password may be wrong use the "Forgot your password?" link on the login form, and you will receive a new password.
