First, talk to your sensei and see if he or she wants some help. Second, I agree with others just start doing things. Third, Lynn is right, nothing will work if the head of dojo isn't into making it better; however, they might have given up after years of apathy from the student population. All it takes is one or two students to motivate a down trodden sensei. Once they get more motivated, they will start putting themselves more into the dojo and then the rest of the students will start putting more in. And it will cycles upwards instead of downwards.

Oh, and finally, it might take a couple of years of prodding for things to start getting better, but have faith and stay motivated, you'll see results eventually, just take things one step at a time.
