If you guys remember, there were two people watching Potripper's table. One is #363; the other is assumed to be Potripper. That second account's email address is [Email]scott@rivieraltd.com.[/Email]
I have talked to a lot of people around the poker world about the IP address used by #363 and the rivieraltd.com email. The IP address cross-references to someone named Scott Tom, who also appears to be an owner at AP. It should also be noted that the first part of the rivieraltd.com email is "scott@".
