Add 4.5 Gigabytes to Your Dropbox for Free
Lifehacker has a great post about adding 4.5 gig to your Dropbox by participating in a beta test. It does require a bit of work (uploading 4.5 gig of files for the test), but I already got 2 gig in upgrades in about 2 hours. Warning: this is bandwidth intensive, so if you are on a pay for use plan it may not be for you.
