I just went into Facebook for the first time in a couple of weeks and I happened to notice an Ad at the top right for a DNS service. Now isn't that suspicious, as I just happened to mention this topic in the group last week and I've sent a few emails on the subject. Where did it get the data to make the association, from my Gmail, from forum posts, or where? I don't know why more people are scared out of their pants by things like this -- Greg K
