How to create a shared area for non-Dropbox users.

I am needing to provide a place for a couple of videographers to upload files to my Dropbox so I can include them in my edits. When I created a shared file and sent it to them, they respond that they are asked to create a Dropbox account of their own to access my link. I just need them to upload their video files to my account - they don't need to have their own Dropbox accounts. Is there a way around this requirement to create accounts for these non-Dropbox users to access a shared directory?
