For those following this thread, we had a meeting this week @iamjessklein and I about how to set up the meetup in NYC. We already have 2 possible venues, one that can host 15-20 people and the other one could go up to a 100 if necessary.
We were thinking of setting up a call for speakers to see who would like to present something and go from there. So please forward the invitation to anyone in the city or visiting the city that would like to present their open source design stuff.
As for communication within the organization team, we are still planning to keep this in the open on this forum for now. Maybe we'll ask admins to create a sub-category, of Local meetups, called NYC to keep our messages together. But we'll see how it grows.
