I get letters all the time asking how people can gather information regarding someone's e-mail and URL when they come into the page. I tell them that you can't grab that information without permission. This will do a nice job of asking.
Please note: This script is being offered in simple text format. When you click to Grab the Script, the text should display. Internet Explorer and AOL users may get a blank page or the script may run and produce the effect. If this happens, choose SAVE AS from the FILE menu and save the blank or compiled page.
