"Unfortunately there is no option 'Add Organisation' anywhere in the User Directory. Bug or Future feature?"Are you sure?When the user is not already in an organization you can add them to an Organization:Agent Panel > User Directory > User e.g. "osTicket support" > Organizations > Add OrganizationUnfortunately you are correct, that it not possible from the Organizations itself to add an user, you have to go to the user and add the organization there - the other way seems (currently) not possible.Beside, there at the organization you can also remove the users from an organization.
