I'm part of a team of Microsoft Most Valuable Professionals (MVPs) who are taking requests for ASP.NET samples as part of the new By The Community, For the Community feature on www.asp.net. The idea is that visitors vote on the suggested item. Then, the MVPs have a couple of weeks to bang together the code which becomes free for the community to use, cruise, lose, peruse, and abuse. <grin>
I voted for "Adding MSN Search to your website" but the "Event Organization site" seems to be the community favourite as of this writing.
My chance to write a sample comes later in the summer. In the meantime, vote for the application or module you want to see first and send us suggestions for the later ones!
