I would think most people have this already. But if you don't, now they give an extra 500mg of storage in addition to the free 2g when you sign up through a referral. Anybody that signs up through you, you get an additional 500mb and so do they.
I use it on all of my computers, ipads, and phones. Invaluable tool...FREE
use the link and get the additional 500mb...and yes...so do i.
