Primary group for local users
Virtualmin can also manage local users on your server, which can be useful if you'd like to use Virtualmin just to manage mail and home websites. With a little re-configuration, Virtualmin can provide an easy to use interface for adding mailbox/website users whose website can be reached via "http://www.domain.com/~username". This is not the primary focus of Virtualmin, but it can make mailbox and website maintenance for ISPs easier.
