You can use the BrightAuthor Manage tab to manage players on your BrightSign Network account, as well as the players on your local network. The Advanced Tools window (accessible by navigating to Tools > Advanced) offers additional player management options.
If you don't see BrightSign Network features in the Manage tab or Advanced Tools window, ensure that the BrightSign Network is enabled in Edit > Preferences > Networking and sign in by navigating to Tools > Sign in to BrightSign Network.
