Lisa, This is a terrific site (I subscribe to digest form as it's easier for me). It's run by a veterinarian, and frequented by many as well. They will NOT diagnose, but will aid people looking for the best possible care for their pets. I signed up a long time ago, but think you send a blank email with subscribe in the title line.
