Although multi-tenancy been one of ContentBox's most requested features, we were hesitant for many years to comply due to the size of the needed refactoring. However, we have finally created a great base for making ContentBox multi-tenant. You can now configure 1 or 10000 sites under the same ContentBox umbrella. The new installer actually creates two sites for you: a development/staging site and a production site. That means that you can manage different content environments all under the same deployment.
