some OrkBlutt (i think that was his name) character made a plugin to get their IP but the other user had to have the plugin aswell. which i spose makes the plugin useless. But i do remember the was a program that could get the IP of someone. it sent a file first thenit canceled straight away and it would use like netstat -n or something in cmd prompt and search for a new Connection Request or something. maybe look it up on google
