It's been a long time, but

I don't think he was banned he was never a controversial guy,i remember he had technology issues,could have just got frustrated with some of the glitches here.So many have left here for so many different things,Facebook and other forums have claimed a lot.

Yes, he was a big proponent of the Revell/Monogram kits (which also have vanished).

He left (or was locked out of) the forum in one of the changes that occured several years ago, but came back briefly as "Sgt. Rock Fury".  Then he vanished again.  Not sure why.

Here's a link to his information, which contains an e-mail address.

  Not sure how much luck you would have with attempting to contact him.  Others may have further information.
