I got a reply from the mod, and he indicated he has thrown in the towel, for a combination of reasons including the cost and hassles involved with keeping the board afloat and the changing legal landscape (including Seattle's aggressive stance toward backpage, as well as problems encountered in NM by the moderator of a board that has some similarities to TRB).
I certainly can't blame him for calling it quits. But I also hope that this or another board provides the ladies and gents the enhanced safety and congeniality that TRB offered for many years. My best wishes to the mod and to all of you reading this. From the volume of posts (or lack of them) here I can only assume that many ladies and gents are suddenly feeling more in the dark and on their own than they did a few weeks ago.
