site update: please try out paper loading

Dear All,

In between teaching - we have been making slow and steady progress.   
We have now (re)implemented the paper auto loading feature.  Please  
go to opensource.mit.edu and if you have a paper to load - please do  
so and try it out.

I am also working on an semi-automated deletion feature - without  
having the need to have accounts or passwords.

Please give it a go..

Tx
