I recently found out about Copy.com. Its like a new Dropbox, but tries to be better, I am still testing it and once I do all my testing I will write a review here.
But for now, there are two things that I found very interesting:
1) Because they are starting and they want to get themselves known, they are giving away a lot of free space. For example if you go to Copy.com you get 15 GB of Free Space online. If you go through the link on this post you get 20 GB. So this means that their referral system its really great, they give 5 GB for each person you recommend. (Dropbox only gives 500 MB per referral) and even they limit it to 18 GB. I already have
115 GB 535 GB of free storage on Copy.com because all the people I referred. You can refer as much people as you want (no limit) 🙂
