ACDLabs users: you may login with your username and password and send files to anyone, in or out of ACDLabs.
Non-ACDLabs users: you cannot log in, but can still send files to ACDLabs users if you know their email address. Start by clicking the "Drop-off" button.
ACDLabs users who wish someone outside ACDLabs 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 28 days.
