Hello, I just wanted to toss out a suggestion about the "Course" page.
Currently you have this listing:
From a learners perspective, I would like to see another tab that basically guides the learners by drilling down through the OSI and TCP/IP models. The objective is to map the target concept, hardware or software to the course episode(s). I appreciated Ronnie and Wes' diagrams that identified the association to the model. Just a suggestion. Thank you for all of your awesome work!
