I need help finding a program I've been searching for. I know they exist as I've seen them in use in html chat rooms. The program I need is used to get an IP address from a person entering an html chatroom such as found in alter realm, creative chat, or any html chat room. This can be done straight from teh room text screen without need for pulling the site logs. The purpose of this need is to identify fuallers or malcontents, not to be used for any malicious purpose but instead to help police chat rooms from teh troublemakers. I've tried searches for these programs but to no avail and any help or links would be greatly appreciated.
