I third DA. Plus if you sign up you have extended viewing privileges, but in order to have max privileges you need one of their premium accounts (whatever the "best" is).
I have a regular acct. but never use it. Nothing posted, though that might change w/ gmod and some silly stuff one can do with it.
Gmax has tutorials and forums and people who can help (I think) for 3-d modeling in general, though the majority of it is probably tailored specifically for their (free) program. Couldn't hurt to check it out, though.
