Yes, there a hidden forum which is only visable to the members I choose to send a proto type head to, for testing purposes. The reason its hidden, is so that we can discuss testing procedures, setups, and results between oursleves, without having to answer 1000 questions by the rest of the forum members. Once the testing is completed, I'll be posting the results, and not until then. There is much to be done in the mean time, so please have some patience, and let us do our work. Thanks.
