The LINQ IQueryable Toolkit is now a CodePlex project. 

http://www.codeplex.com/IQToolkit 

Going forward this will the be official site to find the latest greatest source bits.  I'll continue to post here about the toolkit, how to use it and to show off new features in this blog, but you'll have to follow a link to download.

You can also start discussions over how utterly fabulous the source code is and how you can't wait for the next drop. 

It's up to you.
