If you're a student with a .edu email address, you get 500mb per referral instead of the normal 250mb. Pretty sweet deal. You can get up to that 10gb limit a lot faster. Also, I just found out that for students, the cap is 16gb, and not the normal 10gb, so if you're a student, jump on this. Here is my referral link, help me out! http://db.tt/1fAfGwA Even if you don't want dropbox, sign up, download it, Ill get the extra space, then you can just delete the account.
