Okay, but I voted my shares through my broker, and obtained my control number for said shares on-line as the number is in the voting form. I then sent that control number to computershare (today), and thought that would be enough to get their control number for the meeting, not to vote my already voted shares, but for what I hope will be a better streaming service (less viewers?) and for the right to submit questions.
I see (now) where the wording suggests sending in the "legal proxy" form letter that you posted as being required. If so, then yes, I agree, it's probable too late to start now.
We'll see.
