RnDr FOX: I have to say I COMPLETELY DISAGREE with your statement. In my opinion makehuman is cheating. At this stage he should be worried about improving his modeling skills and learning about things such as edge looping, not having a program do it for him. I feel it's cheating, as the point of 3d art is to create your own art, not have a program do it for you.
I'm sorry but I do not support makehuman at all. It's a bit like when people make art out of poser models then try to claim it as theirs.
As for a tutorial, the
Joan of Arc tutorial is one of the most famous. It's not particularly an anim8or tutorial, but everything they can do can be translated to anim8or, you just need to know your way slightly around the program. You can always ask for help with specific questions (first trying to figure it out yourself of course). Then you could find a horse tutorial, and only model the lower body, then merge the two objects with the knowledge you then have!
