The kids at COLAGE are doing their own bit to help the fight on Proposition 8. They are having a postcard campaign:

2. Create your message. Keep it short and simple. Here is an example: Dear Uncle Ron. On November 4th when you go to vote please remember to think of me and my two moms. Prop 8 would take away our rights as a family. Vote No

Short, simple and to the point. More power to them.
