The 2009 Summer Scripting Games will open today. I am going to participate and try to golf the entries as well.
Announcements of the events are a bit hard to find, though. I only started today since I didn't know they were already at event 5. But officially they begin today.
My solutions to the individual events can be found in my SVN repository.
Update (2009–08–06): I won a signed copy of Windows Powershell: Step by Step.
