How do I change my profile?

Go to your "My Account" page from the dashboard when you are logged in. Look for the "edit" tab.

The first page you are brought to you can change your username, the e-mail associated with your account and a few other settings.

You can also modify your "Contact Information" and "Extra Info" by clicking on the links under the "edit" tab you clicked before.

Remember to save the information on each tab that you are modifying before you go to the next one.
