I can't find the original thread talking about whether or not a sex board would be a good idea.
But I remember that a lot of us talked about the likelihood a lot of threads being posted in Chat (or elsewhere) instead of in the Sex thread.
And this is exactly what has happened.
One posted today in Chat because 'too much identifying information' and therefore the OP wanted it in Chat because it would be deleted after a certain period of time.
Given that a lot of us didn't want the sex threads so actively visible, and therefore you created a Sex board, how about making the threads in that board deletable after a certain amount of time? In which case, you could then move them from Chat to the 'right' place.
