The wiki software can be configured to serve multiple "virtual" sites from one running server. This allows one server administrator to host sites for many users. Here we consider the various ways such servers can be configured in order to meet the needs of various communities.
This wiki innovates many of the conventions you know. If this is your first time, please allow a little time to adjust. It feels a little disorienting, but your patience with that discomfort will be richly rewarded.
