"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Remote user is only set when the person has been through http user authentication.  When the user enters the private web pages the server asks for username and password.  If the user is allowed access then Remote_User is set to the username.
If you want some info on who is sending the form, use
REMOTE_ADDR to get the ip address or
REMOTE_ADDR to get the hostname
That is all that is given about the user to protect privacy.  The above information could track the user down if the authorites got involved.(by looking at the logs on their ISP)
Comment back if you have any questions.
