Guest types are assigned to arrangers in the same way as regular users - within the arranger's own account.
Create a new Guest type (see Manage Users | How To: Guests - Create Guest Types).
From the Company Tools toolbox on the homepage, go to Manage Users → User List (in the main menu).
Select the Global Arranger or Arranger (e.g. "Joe Global Arranger") you would like to manage a certain guest type. This will open the arranger's own profile.
Within the arranger's own profile, scroll down the page and click on Update [Arranger]'s traveler list (for example), then Add additional users to [Arranger]'s traveler list. Check the box next to the desired guest type (e.g. HR Recruit) and you're done!
