Beginners tutorials?

Hi everyone,
I have been using 2d cad and graphics programs for a few years to produce files that work for CNC machining and I now want to produce some 3d work. I have tried various 3d programs but find it quite difficult to grasp some of the concepts. I have downloaded MOI and I quite like it, and it seems easy to work with. But it would be really good if there were some beginners "start from ground 0" tutorials on the various controls and methods, also, is there any more documentation ready yet?
Regards
