I receive an email news letter from the Angler's Covey in Colorado Springs. One thing I really appreciate is information like in the link below. This will take you to a form from Trout Unlimited that is very user friendly. I don't know if it actually amounts to anything as far as our congressmen but it is quick and easy.
