You have to double click on the thread page.
Start from scratch:
http://www.mcarterbrown.com/forums/
Then click on the forum you want. Say "Ask the Experts".
Once there, you see a page with a list of discussions right? That's where you can double click. Click right next to the title of the discussion, and you should be able to edit it there, and it will transfer throughout.
Give it a go, and let me know if it works for you.
