Disillusioned JW - "I wish there was a way to find out who are the JWs with doubts and who are the disfellowshiped JWs (ones considering reinstatement), so that we could contact them and share with them what we have learned."
They can only do that themselves.
Take heart, though... sooner or later, they do.
How else do you think most of us ended up here, after all?
