As a feed-back, I had to opt-out with one account because of the sticky ad at the bottom that prevented me from using voting with several accounts. It was impossible to use this function because when I scrolled to go to the bottom accounts the sticky ad was in the way. When I closed the ad, it also closed the window for voting with several accounts. It's a small thing and maybe it's possible to change something in the design so that things are working again. Also it's probably not a problem for most users that don't have more than 20 accounts like me :-)
