If you have any specific questions I would be happy to answer them! Once you have a particular question do a search here on the website to see if it has already been answered. If not, post a new discussion under the LEAP forum.
I'm afraid the answer is "no - not yet". We are currently storyboarding some short videos about learning to use LEAP and hope to start creating them in the coming few months. Once they are finished we will make them available via this web site.
