For all you Dropbox users, every referral you make will now net you an extra 500MB (up from 250MB) of storage space. From the Dropbox blog:
Today, we’re really happy to announce that we’ve doubled the amount of free space you get for inviting friends to Dropbox!
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!
The best part about this increase in free space is that all existing referrals you’ve already made will also count. So if you previously had 6GB of space on your free account, you should now have 12GB for storing ebooks and other documents.
