Also, a very good post with brokerage contact information:

If your choice is to vote Green (which means Change) please follow these very simple instructions:

1. Tuesday Dec 18th, call your brokerage house where you purchased your shares, and ask for your Green Proxy Control Number. Do not let them say no, do not let them delay. If they try, call back for another Rep, if still no luck, ask to talk to their Manager! You Must get these ASAP! If you're having troubles, please PM Sculpin, Molson, or Bow2u, or post it, and we'll look into it.
2. I recommend writing down your 12 digit control number, right above your 12 digit number on your white proxy form. Be sure that they are different numbers! Remember, you need a different Green Proxy Control Number, for each different account you have!
3. Once you have your 12 digit number, then click on this Link https://central-online.proxyvote.com/pv/web.do?pvskey=proxy
4. ProxyVote page will appear. Enter your 12 digit Control Number & click submit
5. Scroll down to the blue back filled box and click "Vote My Shares Per Opposition's Recommendations" (only if you agree with them all)
6. Scroll down & enter your email address in the blank box, so you get a verification email
7. Then click on "Final Submission"

It is that Easy!

Now please Do Not delay, if you want to see Change (Green Proxy)
