I’ve just posted a new video tutorial on www.thedemo.ca, which demonstrates some of the possibilities available with the access controls available for TYPO3 administrators and site editors.
Administrators can be given access to everything, access to only certain pages or sections, access to only certain functionality; even the left menu can be trimmed down to display only the controls that they require.
The site used in the demonstration is that of wellspring.ca. This is quite a large site, with 3000+ pages and multiple administrators. Each site administrator has access to only their particular portion of the website: for example the Toronto administrators can only see and update the Toronto pages, calendars, events, etc; the London administrators can only see and update their section of the site, etc.
