Multiple sites sharing global templates Our university is made up of many small sites.  I'd like to use craft for this.  Love the auto update feature.  I want each site to share template styles (ie. staff directories, document listings, etc.) but I want to be able to update this global library of templates as time goes on so all sites have access to the latest options.  Also being able to make a change to a global navigation and footer and have all sites updated at the same time would be key.

Does anyone have any suggestions on how to achieve this?
Global templates are absolutely possible by taking advantage of the Twig {% extends %} tag. You can read more about template inheritance in Twig's documentation.

If you set up multiple sections, you can assign certain users edit privileges to their appropriate sections.

You can set up your navs and footers as Globals (or use a plugin), you can set editing privileges just to admins. Simply create a header and footer partial template and include them in a main template file that your other templates extend.
