The site administrator has a "SuperUser" Joomla account, called suttonpoyntz; this gives access to all of the Joomla features (most of the accounts that have been created give a subset of features, and do not, for example, allow the modification of all the user accounts).
In addition, the site administrator will need access to features provided by the site host (currently One.com), and so has a One.com Control Panel account. This Control Panel is accessed via https://login.one.com/cp/ , using account
Separate passwords are needed for the SuperUser account, the Control Panel, and FileZilla. These are known by Bill Egerton and Jez Cunningham.
