I also recommend ramsdaj28 to be in the list. He's a great campaign manager and designer, and probably one of the most considerate managers I ever worked with.

Here's ramsdaj28's profile:

I also agree with most members that Yahoo is one of the best, if not the best, campaign managers in the forum.
