Oh Donna, it's always so bitter-sweet when a foster leaves to start their new life in their forever home.  Thank you for all that you have done for Molly Joy.  I'm sure the couple would agree to send you updates on her progress.  I have heard from all of foster's families, and get occasional pictures.  I always try to remind myself that they will be "top dog" where they are going.  At my house they are loved, but they are just one of the pack.  Each dog deserves their own "person" to love them.  You, my friend, gave her roots.  Now you are giving her wings.
