I've been studying PowerShell and I've been (slowly) getting it into my day-to-day DBA tasks.
So far I've seen a bunch of disconnected PowerShell scripts for many disparate administration activities.
What I'd like to know is if there is an official (or recognizable) PowerShell scripts collection or repository that people usually go to for SQL Server PowerShell scripts for common DBA activities (something like Ola Hallengren's T-SQL scripts).
