I believe it is an issue of being logged in or not. If you are logged in, you do not get the notice. If you are not logged in, you do. I just tested it and that is what I got. If this doesn't resolve it, post back and an admin with more tech skills can look into it.
"Twenty years from now you will be more disappointed by the things that you didn't do than by the ones you did do. So throw off the bowlines. Sail away from the safe harbor. Catch the trade winds in your sails. Explore. Dream. Discover." - Mark Twain
