I got this from their website: Legislation is pending in the U.S. Congress authorizing $20 million in federal funding specifically to help local YMCAs serve more at risk teens. In order to make this bill law, IT IS CRITICAL YOU WRITE YOUR MEMBERS OF CONGRESS ASKING THEM TO CO-SPONSOR THIS LEGISLATION! Simply click on "Contact Congress" to send a pre-written form letter. You can also send a letter inviting your representatives to visit your teen programs. It couldn't be easier! Click here for more information.

Who do I contact if I have a concern about my Y?
If you have a concern about your YMCA, please contact your YMCA directly. If you know a volunteer or staff member at the YMCA, share your concern with him or her. If you would like to pursue the issue further, we recommend you contact your YMCA's executive director or chair of the board to talk about the matter. He or she will be willing to listen to your thoughts. Or you could write a letter directly to the chair of your local YMCA board because the board oversees the YMCA. If you are complaining about something at your YMCA, it's helpful if you offer a solution.
