Domains will be here. A wizard will have a private place in /w/xxx, and may
belong to a domain. The 'Standard' domain will probably disappear.

A domain can be created (manually) by the game administrator. If he wants
to give access permissions for wizards to a domain, their names
should be put into the file "/d/domain_name/MEMBERS". One name per line.

It is recommended that the domain name contains a capital letter.
