Dropbox "upgraded" our account, resulting in our folders being completely reordered and permissions being changed. We fed back this issue to Dropbox and we just got an email lecture on how Dropbox thinks their "shared team space" should be used best. Hey Dropbox - difficult to share folders if permissions have been removed! So we now have to put a lot of time and effort into sorting this mess out. Pen and paper are safer than putting your data in the hands of this soulless corporation.
