oh! one other thing; also look for 'force limits =0' and change that to a 1, for that parameter. (or for that body part, not sure where exactly it is.) then if people turn off limits, they still can't x-rotate your piece. um, just be really REALLY sure nobody would EVER want to rotate it, or you'll drive them nuts. ('course, if it's something silly, they'll already be nuts for wanting to do it, but... ;) )
