Hello
I would like to recommend very good cloud storage site similiar to Dropbox but imo better - copy.com.
When you register you have 15GB storage for your files, with a link from someone who already have account you wil get 20GB.
Copy.com have app for Windows, Android, ios and other systems, works pretty well testing it from last 2 weeks (mostly Android) and have no issue so far with it
With Dropbox you can increase your storage but it really painfull and slow but copy.com from each person that register from your link you wil get 5GB free, lets say 100 people register and you get 500GB storage, lifetime
If anyone try out it please use my link and you will get 20GB instead of 15GB

P.S. To get extra 5GB you have to register, confirm email and install copy.com app on any platform (windows, android, ios)
