Hi Bin,

You can now earn twice as much free space by inviting your friends!

For each friend that installs Dropbox, you’ll both get 500 MB of free space. You can earn up to 16 GB.

Invite your friends now!

Thanks for spreading the Dropbox love,
- The Dropbox Team

P.S. Already invited a bunch of people? Don't worry! You'll get credited for all of them.
