Johnar is very right. Honestly, Anim8or is probably the simplest best organized 3D software out there. Once you get to professional level programs there are so many features around that the interface just gets plain complicated. With Anim8or (and other programs for that matter) it's also very useful to learn the shortcut keys, they can speed things up greatly, and take away from some of the complication.
Really it's just a matter of practice. Any program will begin seemingly complicated, but after some use you'll understand why things are organized like they are, and how to use them in the quickest and easiest ways. It's a matter of use and practice.
As for the forum, again practicality is the key. It may not be the most attractive theme to everyone, but it isn't ugly. Personally I would rather Steve was working on Anim8or features than pimping out the site.
