I found out about this site thats the best alternative to dropbox out there its called Copy! You get 20 gb of online storage if you sign up before a certain date, otherwise its a whopping 15 gb
If you follow this link all you need to do is enter your chosen name and email and your set up with an account. They have a great app for windows, mac, ios, android etc.
I love this thing, especially when working on colabs this is much better then the 2 gb dropbox offers, basically 2gb is never enough when working with reason projects!!
