Yes, and No... I just did a forum search on this site (advanced), for davidg, and it took me to posts that he responded to. I picked the first one, about lacquer, and scanned to davidg. I clicked on davidg, upper left, and it brought up a window where I could send David a private email. Doing it this way, I don't believe there is a way to see the address on the first message. Subsequent messages, if he answers, will show his address.
