Welcome jim_bean, Thanks for relating your story.
Kuddos to you for reaching out to JWs. You are smart to only reach-out to the "Spiritually Weak" (still thinking) JWs and exJWs, because the "Spiritually Strong" (non-thinking) JWs would feel too much cognitive dissonance to do independent research themselves.
You have many options to help JWs/exJWs to overcome the WTBTS's BITE control. I would recommend that you read information by reputable cult-exit couselors such as Steve Hassan's books (i.e., "Combatting Cult Mind Control", "Releasing the Bonds: Empowering People to Think for Themselves", and (his latest book) "Freedom of Mind: Helping Loved Ones Leave Controlling People, Cults and Beliefs"), visiting his website on www.freedomofmind.com, and watching his FREE videos on his website. Just sending them emails with pictures of what you are doing (except for parties) might cause them doubts. If you start talking with them, learning how to overcome them using WTBTS's thought-stopping platitudes might help them to start to critically think for themselves.
Best of wishes on your upcoming Birthday(s) - may you have many more B'parties.
Peace be with you and everyone, who you love,
Robert
