Hi Amanda,
I created "clone this" pages with a few basic layouts and instructions written right on the pages to make it "dummy proof" for my users. Basically, they should never "go rogue" and built a program on their own. Just clone the "Webinar Clone This" program and edit the fields to update content and keep brand standards.
In the (more common than I'd like) scenario when someone deletes something or tries to edit html on their own, I have a "cheat sheet" landing page for them with all of the fonts, colors, sizes, links to icon image folders, etc.
It took time to create these assets, and time for my current users to "stop going rogue" but the newer team members LOVE IT!
