The Day of .NET in Ann Arbor has been a successful spring conference for two years now. So successful, in fact, that we have been asked about why we don't hold it twice a year. /shrug
So, by popular demand, there will be a Day of .NET in Ann Arbor on October 20, 2007 as Washtenaw Community College. The Call for Speakers is currently underway (as well as the sponsorship drive for those of you with a corporate checkbook).
