Hi Lee,
I just deleted my own thread "Missing threads - the reason why?" by adding a new post and deleting it.
As I said, if the last poster deletes their thread, the whole thread is getting deleted.
Or is it just me that has this (unwanted) facility?
F 
I can find some of the threads only via search engine, they don't appear on the first page, even if they've got recently posted on. Why's that? 
...and I seem to have lost some of my posts. I've reached 18000 twice!
Not 18,000 again ... are you dying your hair as well?
Lee not know but Aaron has fixed bug, so hopefully now all is good.
For a brief while I had the power to delete whole threads. So that's how that feels.
