I don't think it is personal or related to content when something your write fails to upload to the board you are posting . I suspect that you are on to one of the reasons that across the board it seems postings are way down on all of the Yahoo threads since they up dated their system. iIt just happens, a lot, and Yahoo is doing, who knows what? Shows what happens when you "improve" or "update" technology to make it more "feature rich" . Microsoft has sufferers with this for years, and is destined to become a "buggy whip" in due course. KISS Principle.
My advice, do it again.
Best of luck.
