Microsoft Script Center has started their yearly Scripting Games February 15 - March 3, 2008.
If you are new to scripting, need a brush-up or are breathing scripts, I encourage you to join.
I will attended the Advanced Division in PowerShell myself. Why do it in VBScript, when you can do it much easier with PowerShell? ;) And Perl I do not know.
I'm planning to publish my solutions as the deadlines have passed.
