He was pretty popular on this forum and stuck around the techy PHP areas, just that I need to contact him about my project and not answering his emails: http://forums.digitalpoint.com/member.php?u=1459
It seems that he hasn't been around in DP for quite some time. His last activity was Dec 2, 2006. Why do you need to contact him?
His directory is at qtdir.com and if you compare his latest links (http://www.qtdir.com/index.php?p=d) with the google cache dated Dec 1st they match. He was at v7n more recently: http://www.v7n.com/forums/members/exam.html
