Arduino were kind enough to give us direct access to a developer when he had down time.
A list of suitable projects was made and a small test team was chosen.

It also takes some of the stress off a couple of people higher up in Arduino I think by doing it this way.
In these cases it has also paved the way for some aspects in the future of the forum itself.
