Platinum pass holder benefits?

So I came upon a post on my Facebook page from CP stating that we get even more platinum pass holder benefits if we register our passes on CP website. But when I clicked that link it just took me to CP home page. I looked everywhere but couldn't find anything. Anyone else see this post or here anything about this?

It really doesn't have anything of value yet, IMO..

I tried, too. it just says my number isn't valid. hopefully they get it fixed and add some cool stuff/benefits.

^ Its says the same thing for me too
