I use DropBox all day everyday, If you want to try the pro version for free for 3 months, let me know and I can hook you up. Below is the email that I received from DropBox:
We just wanted to remind you that you can give a free 3-month trial of Dropbox Pro 100 to anyone you’d like. It’s our way of thanking you for being a Dropbox Pro user :).
To send your trial invitation, head here:

P.S. The Dropbox Pro trial invitations expire on August 30th, 2012.
