That may be true, but the animations themselves are not exported unless there has been a very recent upgrade to the program. The author published the custom format for the animation data but to the best of my knowledge nobody has written an exporter.
IMHO, one of Anim8or's strengths is in animation creation, not particularly 3D modeling itself, so you might be better served to start with Milkshape or GameSpace, where you can create models and then animate them in a DBP-friendly way. I don't know anybody who wouldn't say that 3D modeling and animation require some serious investment of your time to learn, so you might as well spend it all in the same program if you can, at least starting out...
