Hey,
I recently went through the Lithium training. I must compliment you all, the training was incredibly thorough and well put together. However, I did have one suggestion. I'll preface this by saying that this experience may have been a result of me going through the training before our community had been built, but it would have been great to have a testing environment to go and play around with some of the tools I learned about in the training to enhance my retention of the material. The videos were very clear and provided a thorough walkthrough of each action, but for those of us that learn by doing very little of the information was committed to memory.
Thanks!
Graham
