I've opened the bug tracker for submission. So, when you find a bug please post it there.
Note that new features should not be posted as bugs. Instead submit a request in the Open Discussion forum and we'll talk about it.
Also note that the TestHarness is far from done, so the reason for opening a bug tracker alread is mostly to catch as many errors early on as possible.
There is now a simple project homepage up and running. I will mainly use it to present documentation about how to write tests using the harness.
