Thanks to Josh for organizing this. In addition to the offical Microsoft One-Liner contest for Exchange 2007, Josh has started his own scripting contest for PowerShell and Exchange. The best part about it is, that the winner gets a signed copy of the upcoming PowerShell book from Bruce Payette, one of the leading designers of PowerShell!
Wow, nice job Jeffrey and Josh. So go forth and submit some scripts to both the official contest and Josh's. To sweeten the deal, if you end up winning either contest, I'll put your name, company, winning entry etc. on the official team blog (2 million readers per month), my blog, the Exchange Wiki and the PowerShell team blog... the publicity and fame alone is worth at least a few thousand dollars of advertising money :)
