Ecoman,
I wrote pretty much the same thing earlier but opted not to post. All I'd add to your suggestions is to not hang your clothes tightly together. Allow some space for air to circulate. If you have to shove clothes to one side to place or remove an item on a hanger, consider donating some of the stuff you no longer wear to a local charity of your choice.*
Good idea. Obviously great minds think alike. I just beat you to the post. Lol!
