A domain can be accessible by several users online and at the same time. The Administrator can define as many users as he wants to perform the administration of a site. The domain is managed from the central manager. Each domain and sub-domain has its own administration and is managed according to the levels authorized for internal or external collaborators. Via a secure access code, the Administrator creates several hierarchical levels for the various administrators to whom he will assign specific authorizations to perform the tasks assigned by site. The implementation of an administration tool centralizing all the data and content of the various sites affiliated to the domain that makes up your client's network saves time and simplifies the organization of the administrators' work.
