I just read about http://Minus.com recently. Apparently Minus offers 10gb free storage (1gb additional for each invite up to 50gb) with 2gb file size limit and Unlimited transfer. They also have user profiles where you can make publish files and folders 'public' and upload files through different tools and applications here: http://minus.com/pages/tools It's 100% free and a cloud startup, and they keep files forever. Check it out today!
That's Rubbish! I tried it now and it work fine. Thank you for the very good share. I was trying to figure out if Dropbox or Imgur or these one. I just have a good list for what can be a good free backup site.
