Is there a set of ER "bonus reports" available for downloading somewhere?

I have a vague memory of someone from Quest sending me a file or download link which added a bunch of additional reports to Enterprise Reporter. They will built by Quest (I think).  Anything like that still available?  Or is everything that comes with the product is whats available?  

Secondly, is there a community of reports that other users build around here that you can share, upload and download?
