GD How to read members previous posts from the phone app

I don't think it is possible from the phone app.

Actually I was wrong, it is possible.

First you click their icon to get the page about them. Then their name appears in the top red bar where the thread topic usually is. Tap on their name on the red bar and you get a menu option of seeing their (new) Posts or Replies.

Great for hunting down spammers.
