I think Notch should make you able to dye your wolves' collars. He should also make a gigantic world where anyone can play with towns and stuff where everyone has a job to do. He should TOTALY make dragons too! You should be able to train them like wolves and ride them. (not like a pig though, you should be able to steer.) They should drop things like diamonds or scales. They should follow you around even when you are not riding them. They should be able to fly and breathe fire! They should be found in large caves with gold , diamond , and other riches. I hope Notch reads this! Feel free to post your ideas too.
The next time an authority asks me, "What could possibly have given you such a lack of respect for the value of human life?" I will respond, "Sir, have you even BEEN to the internet?"
Look up some SMP servers.
ALSO, ever heard of multiplayer?
