I can't seem to add any cards; when I look at the button in Google Chrome's "Inspect Element" thing, it shows that it passes some javascript and then for html a "#". I'm running the latest version of Chrome at the moment. I tried IE, but as soon as I add a card, it does nothing, and it collapses back to normal view. What should I do? When I click Add Cards, it does nothing.

Nevermind - the add-on "Troll Emoticons" was the cause of the problem. If you have this installed, just disable it until you're done adding cards. This app tends to cause quite a few problems... kind of amusing when you think of the title of it.
