Laura, I just found out something: when floating a board you're asked to confirm it from inside the board itself you are asked to confirm it. When unfloating, you are not. I would expect either that it would be the other way around or that both would require confirmation.
Why is this important? Well, my normal MO is this: I have several boards of interest floated and I log in several times a day, see if there are any posts of interest and after skimming all the new threads, I clear the board so that I can easily know when there are new posts. When I did it now, however, I accidentally unfloated the board instead of clearing it. In this case, I realized my mistake immediately, since I saw there were still unread posts, but I could have missed it as well.
