Then how do you expect to be able to see the response to this one?
(Sorry, I couldn't resist that).
I navigate to the forum on which I posted it and click on the My Threads button. There is a My Threads button in the main forum page, but it will only show you your threads that have new comments since you last visited them.
BTW, My Threads is all of those you have posted in, not those that you have started.
