OK, been searching for over an hour. It's not me. The advice given by mods somewhere here posts jpgs of discontinued search page. I simply want to find all posts started by a member. I can only see a way to search for all posts by a member. Not helpful to me. I can't believe this issue hasn't come up.
You want to see all Threads started by a specific member, if I understand correctly. Go to the member's Profile Page, go to Postings and at the bottom it should show Find all Threads by xxxxxx.
