This is how I found it. I heard on the news last night that a list for the my county and a couple of others around me had been published so out of curiosity I googled it. What I got was several hits for a site called Fairfax Underground which is a forum mainly for and about Fairfax County, VA. Someone who calls themself Mrs. Snowden posted the lists. I have no idea how to find any other consolidated lists. This one had name, address, city, state, zip code and email address and was sorted by zip code.
I feel for the families affected. I knew my DH would never do anything like that, but not everyone has the same commitment/relationship we do. DH and I discussed this site and it's so far removed from an "oops" affair or even how a lot get started, as friendships. It takes forethought and planning and intent, all which for me would be deal breakers. I do think the fallout is going to be pretty dramatic and think about it, every time you hear about a divorce in the next year or so, this site will come to mind.
