Trish, in the navigation, under Classes, there is a new DIAMOND section. That is only visible to the DIAMOND members when logged in. If you click on it, you will get a sort of “overview” of all that your membership gives you access to.
The individual tutorials were part of the Creative Scrap, and you can access them through Classes > DIAMOND > Tutorials – Previews (the alphabetical list is not ready yet).
For the ones with the Notebooks, those are Lab modules, so you can access them through Classes > DIAMOND > The Lab.
Is that a bit clearer?
When everything will be in place, I will make a little walk-through.
