Does anyone know how to automatically get someone’s ip and send it to you without them knowing? Email me at alexn817@hotmail.com or click here. (http://www.anzwers.org/free/alexn817/messagebaord.html)

Also, I tried the script at this site (http://javascript.internet.com/user-details/visitor-monitor.html)
but it didn’t work.
