The web Administrator can manage several domains. The architecture of Catalogger has been designed for this, it is not a plugin. The Catalogger administration module has been designed so in order for the web Administrator to manage several domains and their contents from a single login and to switch from one to the other in one click.
All content generated from the multi-site manager's backoffice is "pushed" to remote sites. Thus, unlike other multi-site solutions, in the event of a fall or hacking of one of the remote sites, there is no risk of disrupting the entire concept.
