Thanks Cathy! I already knew you hadn't deleted the posts.
According to the report just issued by my assembled team of twelve cyber homicide detectives, a member who had no posts in the Kathy Griffin thread suddenly lost six posts. I know my post from another, yet to be identified thread, was deleted. I'm sure Noel Tyl didn't delete the threads because that's not his style and because he was never logged on.
The tres gauche deleter was the member whose post total dropped by 25. (See my correction ahead.)
But there's still a mystery to solve so I have a proposal. The first forumite who can identify the other deleted thread will win a year's supply of Rice O Roni! It's the San Francisco treat!
However, it's my contention that the flavor can, in fact, be beaten! I'm still trying to come to grips with the song's grammatical error that traumatized me as a boy!
Seriously, I'm not losing any sleep over the missing threads.
