I have some great news for users of the popular cloud storage service Dropbox. Earlier today, the Dropbox team announced that they would be doubling the amount of free storage awarded in their referral program. That’s right, from now on, any friend you get to install Dropbox, you’ll both get 500 MB of free space. For those with a free account, you have the ability to invite up to 32 people for a total of 16 GB of extra storage. Those with Pro accounts will now earn 1 GB per referral, for a total of 32 GB of extra space. Now isn’t that just doubletastic!
