I'm tryiing to develop a Community that provides access to Answers, Ideas, and Knowledge without requiring authentication. I've created a Community and configured the Public Access Profile to give it access to the right objects and tabs, but when I try to go to the Community, it prompts me to log in.

 

I should be able to create a Community that exposes at least some content without requiring users to log in, shouldn't I? What's the trick to configuring that?
