Often stack exchange sites have events to help bring the community together. We have not had any on site events in the past so I am bringing forward a suggestion from chat.
What: The Great American Beer Festival Meetup of 2012
When: October 11-13(Thursday-Saturday), 2012
Where: Colorado Convention Center, Hall D, E, & F, Downtown Denver, Colorado, USA.
Who: All EE.SE Users, their friends, family and acquaintances also.
A meetup.com group has been made but is currently a work in progress. The meetup group allows people to propose times to do just as the name says, Meet up.
Suggested events here would be a great idea, the meetup site is designed to allow you to suggest events there.. I will be editing this with further information about the event as I collect it.
