Am I just too stupid not to be able to find it, or there is no more PM feature on ET? I see the private board, but that can be read by anybody. Or is there a way to make it readable just by the 2 parties? Edit: OK, too stupid I guess, I have found it. It is the Start a new private thread option. I was looking for PM or Messaging...
Click a name. Click Start Private Thread, which is equivalent to PM. A private thread can be seen only by its participants.
