DASH4 registration will open on Tuesday, March 13, 2012 at noon, PT. There will be one central registration for all cities located at
http://www.playdash.org/DASH4/. Registration will close on Saturday, April 14, 2012 at noon, PT.
Teams will be accepted on a first come, first served basis; and, while all cities have a maximum number of teams that they will accept, the maximums are fairly generous.
In the past, 3-5 players per team has been the recommended size. Technically, no reason why you can't have smaller - but, it would make it much harder.
