Any editor in the space can manage the space tag list available for requirements, stories, URL library links and reference model nodes. Go to Space Management and select "Customizations" in the left-hand menu. 

Any editor in the space can create a new tag or delete an existing one. This only affects the list of available tags and does not remove the tag from the items using them. 

Tags cannot have spaces and any special characters like ! £ # $ % etc.
