The list below replicates the example provided on the 300, 667, 0 page. Note how each of the longer items wraps to the next line. Setting the left column to a slightly less narrow width will allow slightly longer entries in a list without as much wrapping.
Note that we selected the X on the Profile Box to "Remove profile from this page"
If you are going to make the right column 0 width when you switch to a one or two column display, you don't have to hide the Profile Box because if the right column isn't displayed then the Profile Box won't display either.
