Anyone may perform the following activities:

Pick-up
Pick-up (download) a file dropped off for you.
 
BWC users: you may login with your username and password and send files to anyone, in or out of BWC.
Non-BWC users: you cannot log in, but can still send files to BWC users if you know their email address. Start by clicking the "Drop-off" button.
BWC users who wish someone outside BWC to send them files, can make it a lot easier for them by logging in and clicking "Request a Drop-off". That saves the other person having to prove who they are. The request created will be valid for 7 days.
