Prisca,
To be sure, I have respect for your decisions with regard to your attitude to the JWs, and also acknowledge that no two people share the same circumstances in life, and I only suggested that you consider DAing whilst having no idea of your situation with the JWs.
I also did not sign on as a member, and neither did I sign any paper when I left as I did not feel it necessary at the time, though, from reading a number of posts here, it maybe be advantageous to drop the society a note reiterating my choice to DA, even though it happened almost a decade ago. Not playing by their rules was a primary consideration when I opted out - I elected to leave of my own free will before they had cause to disfellowship me.
