There are some nifty features on this website under your profile. If you click on 'my account' at the top or side of this page, you'll be taken to your profile page.

Click on 'Edit'. Here is where you find all of the hidden options and also how to change them.

Of particular note is 'Picture'. Here you can upload a small image to be used as your icon for any time you post. You can already see mine throughout.

Also, if you have an Instant Messenger account, there are options to fill in your screen name for AOL, ICQ, or YAHOO. If you do, people will see an indicator when you are online.

There are other options, most deal with your personal contact information and have descriptions on how to use each next to the option.
