It's dangerous to go alone! Seriously; take a friend when setting up those rickety bookcases. Friends can help you build and add their own furniture to your room once granted Design Rights. 
  • In Room Settings, tap on 'Moderation and Access'. 
  • Hit the button 'Add User' and search for a specific user to add them to your Mod/Designer list.
  • This feature allows for collaborative efforts to build that amazing room you've been dreaming of! Designers can edit your room's appearance any time. 
  • Keep in mind that any furniture of yours will remain in the room until you remove it, and any friend's furniture will remain in the room until they remove it. No one will be able to take another person's furniture items, though everyone with Design rights will be able to move them about.
