Someone, or perhaps a few folks, to serve as spokespersons for the event. They would take on the accountability for making sure that the event actually happens, recruit other leaders, approve spending, etc. Basically this person is the central point of contact for the event.
Has this event been cancelled? The BayNET site has a line that it has been cancelled. Too bad, if true. Please contact me if you want to make another go at it, or something similar.
I like the idea of a weekend long hackathon, even if it is just for training.
