ellieoop: Only the weekend days (normally Saturday & Sunday) can be changed every 30 days - I think you can change your vacation days around whenever.... well as long as the date has not passed.

For the smileys, In Settings, JavaScript page - change "Activate interactive smiley window:" from "on mouse over" TO: "on mouse click" That way you can click on the smiley for it to come up, rather then accedently pass your mouse over the list where they all come up, and sometimes have to click to make them go away.
