> I am not a lawyer, but I've received several C&Ds for various things over the decades. The first one scared me to death.

The first time I got a letter for a trademark issue it seemed completely hostile and threatening. My lawyer said, basically, that it was no big deal and that they were in fact being pretty nice. We answered back and everything was resolved amicably. It actually turned out well because it made me realize we had not been paying enough attention and were unthinkingly referencing other brands instead of our own.
