Another difficulty posting threads

Here is why you're seeing so many duplicate posts on the boards, and it needs to be fixed.

I created a post, clicked on "post", and this was the error page I received again...for the umpty-bazillionth time.  It looks for all the world like my thread didn't post...but...if I go to the board home page, the thread is indeed there.  I've learned to check before reposting, but not everyone knows that, especially some poor unfortunate new soul who might wander in here.
