hi, my internet was down last night so I wrote down the stuff I wanted to ask and here it is:

1.
What's the difference in animating nurbs, polys and subdiv?
is one easyer than the other? what is important to do while modeling to get an easyer job at animating?

2.
what exactly are fluids for? I just have no idea at all on what they can actually do.

btw: actually I had 3 questions, but I solved the 3rd one myself!
isn't that great!
hehe
