The only way I know is to have the board administrator
look up either the user@machinename or ip address.
Then with tcpip command like "host <ip>" you can get
the user and fully qualified machinename.
That still probably won't give you a place, but might
get you down to the level of business@city
If they're coming in thru something like AOL, you would
have to have a court order to get that info.
