Adrian Beasley, a member of the UK PowerShell Users Group (www.get-psuguk.org.uk) has contributed two articles on PowerShell to the Industry Insiders site.
The articles cover PowerShell Installation and Executing a Command Line Utility from PowerShell and Waiting for it to Finish.
The articles can be found here. The articles contain good material for every level of PowerShell experience. Nice job Adrian. Looking forward to more in the future.
