The CodePlex CRM Sandbox is a new place to find customer provided CRM code solutions. It has been a project of mine to move the existing CRM Sandbox code samples from the GotDotNet world to CodePlex. And with over 40 code samples, this was no easy task.
I think I've found a very useable solution that makes it both intuitive to use and easy to access the solutions. I have some CRM MVPs looking at the site right now for confirmation. Feel free to poke around and give us feedback. I'd love to hear your comments.
