Passing of Mark Belsterling, distinguished member of the Flex community.

I was shocked to hear today of the passing of Mark Belsterling, one of the main voices of the Flex community in Philadelphia and indeed the world. Mark was the manager of the Philadelphia Flex User Group.

Mark passed on this Saturday, Sept the 8th.

I met mark a few months back when he came over to interview with us at CIM. I was struck by how much Mark knew of all things technology related. Mark had a very unassuming nature but had the experience to humble many veterans in the online domain. And it was really obvious how passionate he was about Flex. He started the Philadelphia Flex User group in June filling a need a lot of us were feeling. He had been having heath issues over summer but still found the energy to organize the meetings for the groups. I met him last at the Air bus tour event at Philadelphia.

I offer my condolences to his family and friends. His presence will be sorely missed.
