This is my first salesforce public site I'm working on.. I've got the page written so it should display my opps on the page, and the site is accessible publically.

I've added Opps to be viewed in the Public Access Settings for the site.. I've even manually shared a specific opportunity with the group that I added the Guest User license to...

Still... no opps appear externally... what else could I be missing?

Is this available for download / installation anywhere?  Reading the book I'd like to see it installed.  My organization is looking at developing a similar app and having hands on access to this application would be very helpful.

I found a similar, but not the same free recruiting app in the AppExchange.
