@ profbtycheek - There is a bug on the Forums where sometimes a thread doesn't show up on a user's profile.
Next time make a mental note of which forum and which page of that forum the thread is in, before you log in, so that you can find it again if logging in kicks you out of the thread. Or copy the Quick Find Code of the thread to your clip board. Then once you are logged in, paste the QFC into the search bar at the top of the page.
