If you are already logged in, click "Account" in the upper right-hand corner of the screen and you will be taken to your user page.
On your user page, select the Edit tab at the top of the page. You can change your username, password, and e-mail address on the Edit page. Other useful things you can set on this page:
• receive notification on Forum posts
• add your picture
• insert comments about yourself
• enable personal contact (a good idea as your e-mail address is never exposed on this site) and private messages
• set your time zone (very important if you are posting events)
Finally, be sure to Save your changes at the bottom of the page.
