Copyright Registration

Hi folks,

I'm not wanting to start a thread about the pros and cons of copyright registration, whether or not it offers protections, etc., etc. I know all those arguments--in fact, I teach a class on that subject. What I'm asking is a simple technical question.

Those of you who have actually registered a Max standalone with the US Copyright office--what documentation did you submit? Did you submit the actual standalone itself, the patcher, an image of the unlocked patcher, a text version of the mxf or maxpat file, or what?

Thanks.
