kairos, when I first posted my JW experiences I had, within two days, a 'still in' doubter, lurker of JWD, and former neighbor recognize me and come to my door - he knew who I was right away. I live in a large apartment complex just full of JWs and I've been keeping a low profile up to now. I myself don't care too much although it could affect me in the future.
Be careful what you say and if you want to get in touch with anyone limit yourself to the city you lived in; the dates you were a JW; and other peoples names that might be lurking here. Still dangerous but if you've got nothing to lose go for it. Oh, use the PM for maximum discretion.
