Comment 4 for bug 770428

I was assuming these tracer emails would just be blog post entries, and then the test would be to verify that unique text, like a uuid or timestamp, was present on the page.

What are the negative consequences of just sending an email to a separate private community? If we want to eliminate the content feeds side effect, we can create a separate dummy user just for this tracer private community.

I guess this makes the test to verify that the mail went through more complicated, but it might be easier to move the complexity there than to build something separate in karl.
