I am not sure whether this would be supported through the site's services but I wanted to suggest integrating a message that warns a user when they are about to leave a page with unsaved text. There doesn't seem to be a current "draft" feature so I believe that a lot of users may find something like this to be useful.
Below are some examples from Facebook and Gmail.
Ex 1: Facebook warning message.
