Dropbox is doubling the amount of free storage you get per-referral to 500MB, doubling the previous 250MB credit–better yet, the bonus is retroactive and applies to referrals you’ve already made.
From the DropBox blog:
How much space is that, exactly? For every friend you invite that installs Dropbox, you’ll both get 500 MB of free space. If you’ve got a free account, you can invite up to 32 people for a whopping total of 16 GB of extra space. Pro accounts now earn 1 GB per referral, for a total of 32 GB of extra space. Have you already invited a bunch of people? Don’t worry. Within a few days, you’ll get full credit for every referral that’s already been completed. Boom!
