Test approval is beginning next week.  Once that is under way, it would be great to get these into GitHub issues so that we  can build them out.  Even better, it would be awesome if you would contribute tests that you felt were missing.  The goal of Ringmark is to be a comprehensive set of tests that include common issues that developers hit on a daily basis-- not merely surface-area testing.

We have limited resources to build out tests though, which is why it's important that we get as many eyeballs on this as possible-- so we can fix the holes together.
