To which you replied:

Perhaps I'm dumb, but could you please explain how that works?

Just to be sure, let me state more precisely what I think is a necessary
degree of secrecy: *Nobody* but me must know whether I voted, what I
voted, whether I named a proxy, and who the proxy is. I don't see how
this can be done in an easy way!

Yours, Jobst
