You probably heard that this year Tech Ed will be 2 weeks long. This leaves a weekend (June 7th and June 8th) in between where there will be a lot of people hanging around. Fortunately there are a lot of events in the area already scheduled and raring to go. One of these events is the Tweener event also called the ]inBetween[ event run by the Florida .NET community. There will be presentations and open sessions for those who want even more. A full agenda can be seen on the inbetween web site.
There are also Open Space sessions where anyone who wants can sign up to speak at a session (first come first serve). These sessions are open flooring and run 30 minutes. You can sign up here for Open Space.
