Steve Schofield, IIS MVP, recently set up a new site - http://www.appcmd.com - which is a great resource for commonly used appcmd scripts.  Appcmd is the new command line administration utility for IIS7.  I've used the Tech Preview of the PowerShell provider for IIS and I use the IIS7 Manager a lot but I still like to work with APPCMD an awful lot and this new site is definitely going to be top of my list for daily checks to see any new content.  Go take a look and let Steve know what you think.  Also if you have any favourite APPCMD Scripts also let Steve know and they may get posted.  Thanks for starting this site Steve, it's a great resource.
