Hour Notes are a way for your content to providers to leave information about their show. Each hour that you have permission to record into also allows you to edit the notes for it.
To open the notes pop-up for an hour simply right click on the log and choose Hour Notes. The note pop-up can be dragged and dropped where you want on the screen and also resized.
To edit a note simply click on the note area and you will see the text cursor. You can only use text and there is no formatting. This is to keep it simple.
