I teach ukulele to a class of of 30 seniors. Can all of them access my song directory, and automatically sync with my song directory on Dropbox? If so how is it done?
They could if they all set up an account and you shared the directory with them via www.dropbox.com/share - either as read only or edit rights. Note, though, if you use edit rights they can delete them.
If, however, they need to just see them you may be better off using a shared LINK instead which they click on and see everything via the website: www.dropbox.com/links
