Does anyone have any tips on learning to micro with Meepo?

I want to learn to become a decent player with Meepo. Just the concept of this hero is extremely interesting and it seems like once you can learn to use him he can me so much fun to play.

However I have hit a serious roadblock when it comes to microing after I get my 3rd Meepo. Anyone have any tricks, tips, suggestions? Im sure i cant be the only person wondering this :)
