Microsoft PowerShell Community Extensions

I haven't had the chance to refocus on Microsoft PowerShell (their relatively new shell and scripting language for Windows XP, Vista, and Server). However, it has been great to see the community building around what I think is a more important development than Windows Vista in the long run. I noticed a collection of what are being called Community Extensions available over at Microsoft's CodePlex site...

Microsoft PowerShell Community Extensions

It provides a bunch of useful PowerShell cmdlets to make the already easy to use scripting language easier and more powerful.
