When you select a programme or create a clip you have the option to add it to a playlist. This is a good way to keep track of programmes you plan to watch or to organise recordings according to subject, course or assignment.
You can opt to create a New Playlist or add the programme to an Existing playlist. Choose whether you want the playlist to be Publicly available or not. Choosing to do so will means that your playlists are publicly available for other users to search.
Any Playlists that you create will be saved to My BoB.
A video about creating a playlist and My BoB is available here
