Instead of the normal 250MB you get from referring someone who signs up for the service, you will now get an extra 500MB of space with a cap of 16GB.
Additionally, the person signing up will get an extra 500MB of free space to start the account, while Pro users will get 1GB with a cap of 32GB.
If you have been making referrals in the past, you will be receiving the new extra space, as well, over the next few days.
Until this week, the "double space" program had been available only to users with .edu accounts, aka students.
