Praet - I have one suggestion for the essay vault for added anonymity. Can users be allowed to post essays anonymously? (where the user name just shows up as anonymous?) I am not sure if there is a way for you to enable this only for that particular forum. This is just because a lot of us go on to meet people off this website when either doing school visits or when they meet as students of a particular school, so they lose the anonymity of the forum username then. I know so far all the contributors have cleansed their essays - but I was thinking this may be good to have additionally.
I think this is a great idea if it can be implemented.
