Launches for SQL Server 2008, Visual Studio 2008, and Windows Server 2008 have started around the nation. They will be going on for the next several months.
There are two kinds of launches.
Microsoft hosted launches: http://www.microsoft.com/heroeshappenhere/register/default.mspx
Community hosted launches: http://www.heroescommunitylaunch.com/
Hopefully, those in the US can find a launch in their area.
I'll be at the launch hosted by the Oklahoma City Developers Group on April 7, 2008. I am currently President of the OKCDG. As of right now, registration is open at http://heroes.okcpro.net. I'll be there, along with my fiancé, and several others from surrounding areas. We would love to have you come.
