Hes not a moderator, and its not a glitch either, just a silly n00b.
He probably had a duplicate account as Omega117 and copied the "[Edited by USERNAME, 5/14/2008 1:24:18 PM]" from another post and simply put "Captordude" in there when he posted it. (just like I have done now)
You can tell its fake simply by looking at the time and dates, the edit time is over one hour before that post was made, and I doubt he has future mod powers.
