You can pay for a WordPress account and get more features, a domain name, etc. So it would be an upgrade from my free site to take the "wordpress.org" out of the URL.

I use Dropbox (almost 8 gig now that I've made a lot of referrals and loaded it onto different devices), Box (both a private one and a university one), and MEGA. But I don't host from those, they're just backup or working files I can share on different projects.
