For example my info:
http://hlstats.theelders.net/index.php?mode=playerinfo&player=61----------------------------------------------------------------------------------------------------
How can I set my real name, e-mail address, homepage and ICQ number?
Player profile options can be configured by saying the appropriate HLX_SET command while you are playing on a participating game server. To say commands, push your chat key and type the command text.
Syntax: say /hlx_set option value.
Acceptable "options" are:
realname
Sets your Real Name as shown in your profile.
Example: /hlx_set realname Joe Bloggs
email
Sets your E-mail Address as shown in your profile.
Example: /hlx_set email joe@hotmail.com
homepage
Sets your Home Page as shown in your profile.
Example: /hlx_set homepage
http://www.geocities.com/joe/icq
Sets your ICQ Number as shown in your profile.
Example: /hlx_set icq 123456789
Note These are not standard Half-Life console commands. If you type them in the console, Half-Life will give you an error.
This next one is for everyone favorite bitch, Barrell 
5. My rank is embarrassing. How can I opt out?
Say /hlx_hideranking while playing on a participating game server. This will toggle you between being visible on the Player Rankings and being invisible.
Note You will still be tracked and you can still view your Player Details page. Use the Search page to find yourself.
