sv_contact

How is sv_contact used exactly? I know that you put a contact email for users in it but how do they access that email and for what purpose does it actually have?

“Provide a contact email address for clients on your server.”

yes but how do clients obtain that email? I know what its purpose is

Pretty sure you just type it into the console and it tells you.

Also, google helps. http://forums.steampowered.com/forums/showthread.php?t=1752258
