And to celebrate, I have added a handful of new PowerShell scripts that can assist with specific Fast Search for SharePoint 2010 administrative tasks to the TechNet Script Center.  They can be found at the link below:

The script center is a great place to find scripts that can simplify IT Pro tasks.
