As far as I've seen you can't, and anything posted on your wall just shows up as " ____ Started a new thread!" and if you click to view this is just loads forever. Profile wise all you seem to be able to do is view profile pictures/change them, and view how many followers/following. You can always just quickly open the forums on Safari or another mobile browser to view your wall when you get the " ____ Started a new thread!" notification.
