I just accidently triggered the auto community wiki by editing my answer to this question:

http://superuser.com/questions/18099/what-should-i-know-to-select-a-power-supply/

I just wanted to point out other good points from other answers even though mine was accepted as the answer. I guess i should have just used comments. And you cannot even rollback.  I guess I know from now on and there is no way to reverse it.
