Super Admin of The Ultimate Training Center - a great vote chess group.
Head of Untitled Tuesday, a blitz tournament for untitled players who don't qualify for Titled Tuesday.
Assistant admin in the Cheating Forum.
Developer of PGN Spy, a chess game analyser for cheater-detection purposes.
Admin in Admin's Corner and Training Club - a club for sharing tips and information with other admins. Highly recommended for active admins, especially but not exclusively new admins.
Suspected cheaters can be reported at https://support.chess.com/customer/portal/emails/new. No public accusations, please.
I have enough active clubs at the moment. I am unlikely to accept club invites.
