He's "Shawn Hogan". DP id is "digitalpoint" (http://forums.digitalpoint.com/member.php?u=1) Rarely comes online though. So if you've got any questions, make sure you've the patience to wait for long time! You could probably message a moderator if you need any help.
If you mean by username, then I guess probably not. There were some similar threads opened earlier, but all were ignored by moderators. You couldn't create new id either, against the rules.
