Hi Joana, Martin and I thank you very much for training Clifford. Your class was really great; we learned a lot about how to make his commands more reliable but also having access to all your advice is priceless. The class was great fun and we’re so glad we took it. We’re going to send off for his CGC certificate (we can send a picture of him with it to all our relatives!!). Thanks again for everything.
