Message Conferences are the top level container for *1:n* Message *Areas* via the `messageConferences` block in `config.hjson`. A common setup may include a local conference and one or more conferences each dedicated to a particular message network such as fsxNet, ArakNet, etc.
Message Areas are topic specific containers for messages that live within a particular conference. The top level key for an area sets it's *area tag*. For example, "General Discussion" may live under a Local conference while an fsxNet conference may contain "BBS Discussion".
FidoNet style `.na` files as well as legacy `AREAS.BBS` files in common formats can be imported using `oputil.js mb import-areas`. See [The oputil CLI](/docs/admin/oputil.md) for more information and usage.
