When you request a user to be roommates, that user will appear in the Room tab as an 'Outgoing Request'.
When the user confirms your request, they will appear in the Room tab in the 'Roommate Request' section. You will also receive an e-mail notification when a user confirms your roommate request. If you have allowed push notifications on the mobile app then you will receive a notification from RoomSync.
If the user rejects your roommate request, they will disappear from the 'Room' tab. You will not receive an email or any other notification that your request was rejected.
