This is probably the most recent one in that series:

The tournament director of the above is : http://www.chess.com/members/view/torbjorngjerde
I would message him.
I`ve signed up for a U1300 speed king maybe a week ago and it was going to start soon. Only about 10 players missing. Since 2 days it totally disappeared. Can`t find it anymore.
Anybody has an idea?
