Thanks for the replies about Sensei.  I was just curious if anyone here was using it.  I won't keep talkin bout it after this post, because I don't wanna derail the thread.  False1, all Sensei is is a deeply customized UI and hotkey design created by someone. It doesn't do anyhthing that vanilla ol Blender can't do, but the way it's designed really clicked with me, and helped me get around in it much easier. It's just a really clean design, with visible icons and stuff for shortcuts that regular blender only has hotkeys for, etc., etc.

heddheld, there's some ill feelings toward it, because I remember seeing some really nasty posts in a thread at blenderartists.org one time.  I can't find the thread now, so I guess they removed it, which goes to say how bad it was.  There's still some comments on their videos by users that are unnecessarily mean if you ask me, and some posts you can find, wihich are again unnecessarily mean toward the creator.  Stuff like this quote:

"I took a close look at the work this guy has done for his promos and tutorials. I notice that the only character animation he has is of the monkey head guy. The head is 'Suzanne', one of the Blender object primitives. Why is he using Suzanne instead of a head he modeled himself? My guess is he sucks at character modeling. Except for his promo, all his other animations are simple fly bys or use the physics engine. Looks slick, but it's not the sort of thing that will actually get you into the nuts and bolts of animation. Take a close look at his castle and his spaceship. My guess is this is the best he can do. Is this the guy you want to take on as your teacher?"

Who says stuff like that about someone in a public forum?  Especially someone they don't know personally.  Oh well.  There's mean spirits floating around anywhere you look I suppose.
