Hello George,
I've checked the Moderator Log and it hasn't been deleted. I've attached a screen capture of the last entries to the log. You'll note that Mod actions cannot be deleted until after 24hrs, and as the Post and thread were there this morning...I read it, so I know it was there...its whereabouts is a mystery!!!
I've emailed the other Mods in case they can throw any light on the matter. I will update here as and when I have information.
Andy
