Here are a few places that you can write:
This is a good place to start. Try posting your comments there to save our soap
or, on the official Passions message board here
You can write directly to the show, expressing your support for the actors and producers at these addresses.
CBS Radford Studios
4024 Radford Avenue
Studio City, CA 91604
30 Rockefeller Plaza
New York, NY 10112
You can also begin your own online petitions to forward to the network at any of the sites below.
Another important place to start is with your local station. Affiliate and local stations carry a lot of weight in matters like this and local support can go a long way. Addresses for local stations can be found here
I will start a thread on the message board for people to post links to petitions, ideas and information.
