Sorry, I'm a little late. Welcome!
I had some of the same initial reservations you had. I lurked for quite a while before posting and I believe it took a day or two to actually post after joining the site. I am still active, and like you none of my family are JWs. All of my husband's immediate family are JWs. I have not yet expressed my doubts to him.
Have you considered reading Crisis of Conscience?
