Hi Charley! You just did it. If it was a test, it worked fine. And you picked an unusually good title for the thread: it really said what the thread was about.
If you actually wanted to do something else, can you say what you wanted other than starting a thread in a forum?
P.S. for other readers:
Charley went into a forum, scrolled ALL the way to the bottom, found "Start a new thread", filled in a subject and a message, and clicked on "Finished".
