I often add to old posts when I find a solution after the discussion has lost currency without being resolved.
Now I cannot find my own posts.
There used to be a control to list my own posts.
When I did this , my response would be promoted to the top of the discussion list and everyone could see it.
Now, if I ever find my old post, my response will be kicked off the discussion list after 4 hours and revert to the history list.
Because I am not in the USA timezone, few people will see my response.
Am I jumping for joy?
