From the site:
"User Samples phase-out – Schedule update in Fall ’07
We will not phase-out User Samples until we can provide customers with a great alternative. We will update you with further schedule information in Fall, 2007."
That's really good news to me. I've got samples I've uploaded there that have been downloaded over 52,000 times. And I cannot tell you how many great pieces of helpful code I've downloaded from other kind souls who want to share their work.
Thanks, Microsoft. You got this one right. In fact, there have recently been fresh uploads of samples in the User Samples area at gotdotnet.com!
Codeplex is great - but not for sharing user samples - unless you want to move the whole gotdotnet.com section there.
