While I added it, I had to make a few tries before it worked correctly, so on Friday it appeared for a few minutes at the top, but since then it should be only on the bottom, and only once (if you click "OK").

There is a EU law that requires that visitors are notified that cookies are stored, and that the sites mention what is stored (hence the "More info" link).
I find a little ridiculous to have to notify users like that, since it is quite annoying to have that message popping on all the sites (at least when you visit them from Europe). A simple mandatory link accessible from the home page of every site would have been enough.
