There are some features of Prosody which are generally for use only by the owner of the server, or of a select group of administrators.

Prosody allows you to specify who is an administrator using the 'admin' option in the configuration file.

For example:

   admins = { "me@example.com", "trustedperson1@example.net" }

Each host can have a different set of admins (simply put the option into the correct host's section).
