Hi
I just wanted to recommend a new subject for your tutorials if possible. :)
You don't do any tutorials on or about the MOODLE online learning system for education. Setting up, implementing, using the various aspects of it for teachers and educators would be very useful and is something that I'm not aware you've look at providing.
I hope you can take a look at covering this very large growth area for education and online e-learning... there are many teachers and educators trying to get to grips with this online e-learning, never mind the admins trying to set it up and implement it!
