But this is different. SharePoint 2007 is available as a public download (trial version) and so is WSS3.
And just so this post isnt just a lame linking post I will update you that I am working on part II for my popular "Simple Code Samples" article. I have some code samples on security, and on lookup fields that I feel are essential to any sharepoint developer.
Also coming soon (very soon) - some new free downloads of some tools I have written for some of my projects to make my life easier.
See you soon!
