I got the invitation in the mail and thought it was just another credit card offer... ;)
Here's the disclaimer:
I respectfully accept the responsibility of serving on the VYB Stewardship Board (VSB). I hereby certify that neither I nor any member of my immediate family has or will claim another membership position on the VSB. I further certify that I will not engage in any sale or ‘quid pro quo’ transfers of ‘votes’ or ‘voting rights’ (i.e. polling rights) associated with the VSB, and that I will not disclose, nor allow to be disclosed, to anyone other than members of my immediate family, the username and/or private key(s) for any anonymous/pseudonymous polling account(s) issued to me pursuant to my membership on the VSB.
See, that wasn't so hard! lol
