I guess the easiest way would be to create a thread for red taggers to post in where they can post images of model runs with descriptions of what it is showing. Once the initial "show and tell" is over with, people could ask questions if they don't understand what the met was saying.
Though, it could be time consuming for an already busy met.
What Adam did for me was he would find an hour on the model run, have me open the four-panel images and describe what it was doing and how to see the differences between a current run and the previous run. It was really helpful.
