Last 3 winners: your email addresses are forwarded to box.com support staff. They will pick it up. You will see the upgrade to 50GB reflected in a few days... DO let us know when this happens! We like to hear good news, here @SCForum!
I also asked box.com if we could run the promo some longer.
Anyone coming here, reserve a possible next spot by replying here AND send me a PM with the email address you used to create your box.com account. You might get lucky ; -)
