re: Possible, you're right. And I'd bet he's not able to do it.
Actually, a friend of mine saw his post in another forum asking "how to" trail an IP address for all internet activity and in his post he described my company set-up etc... he didnt really say it to someone knowing it would get back to me as if to worry me on purpose - he is out there somewhere else in another forum asking the questions to strangers. My friend just so happened upon it in her search for networking answering for her company. Its all a bit ridicilious really - what an ass he is!
