One of the main things you'll do on your FLOW account is create and work on stories. To organize or filter where your stories are going, you can use Story Tag Groups. Story Tag Groups will appear in boxes on the left-hand side of the story page. Some common examples would be Section, Publication, and Issue.
You FLOW account does come pre-loaded with several Story Tag Groups, but you can customize your Story Tag Groups in your FLOW settings. You can either add any additional Story Tag Groups or delete Story Tag Groups you do not need. You can also edit the individual tags within a group, such as adding or removing tags in your Section Tag Group.
You can also set Key Editors for each individual tag. A common example would be selecting your appropriate Key Editors in the Section Tag Group (News editor, Sports editor, etc.). Selecting Key Editors for your Story Tag Groups can be useful later on when creating Workflows.
