I'm going to drop the effort to get a Software/Data Carpentry Train the Trainer workshop just before GCC2016. Hosting the workshop is on the expensive side, and just having 7+ people stating their interest at this time means it's just too much risk for the organizers.
While that will be disappointing to many of us, you can still take Software / Data Carpentry Train the Trainer Training (S/DCTTTT?) through other means. See
Thanks to everyone who considered attending, and to all those who participated in the discussion.
