Its just money, nothing important.
I have gotten a total of 3 mailings in as many weeks about this: the first, "it's coming - please participate!"; second, the intrusive form itself; and then a postcard early this week wondering why I hadn't sent inmy form yet (I'm thinking about it - or not.)
In my entire life I can't remember as much angst being made about this process and as much money being poured into it in the past.
