My best recommendation is to surf the site here as there are some very thought provoking posts, and to reply to those.
Also we do have some courses that will be starting up in September I think, in case you are interested…these have some great material that will help you to broaden your knowledge as a Jedi.
There is, however, Xhaiden’s site, which I’m sure your already aware of at Jedi Online, which has a bunch of different lectures, discussions, posts, etc by Jedi throughout the community as well. this is a personal favorite of mine.
Hope that helped
