I use MyCloud with OS5 to transfer videos to my clients.
The admin interface is fair but can really use some added features.
1 - The ability for the admin to see who is logged in currently.
2 - The ability to see a database of what files were downloaded by each user.
3. An option for the admin to clean (delete) files (or prompt files to be deleted) x number of days after the user has downloaded them.
Thanks
