I thought of it just as I hit the submit button, and I tested it and found it. If you want it sorted by last updated, click on the heading that says "updated", and this will sort either by last updated at the top or bottom. You will get a small arrow that points up or down, make sure it is pointing down. If it is point up, just click on this heading again. Right now, I bet your heading that says "topic" has this arrow, and it is pointing down.

Good luck,

Tight lines and God Bless
