Websites such as YouTube have playlists. With a paid version of RealPlayer, you can download these playlists without having to download individual videos within this playlist.
With RealPlayer Plus, you get 1GB of Cloud storage. It is possible, you might have received 2 additional GB when we had some offer in the past. Your account current shows that you have 3GB of Cloud storage and you have uploaded 2.1GB of files to the Cloud. This is what it means by 69% of 3 GB used.
