Well, it was like this, roger ....
I noticed that there was a BillW posting today & wondered if it was the same BillW I remembered.
So I went to the poster's profile page.
And lo & behold, there was an "I'm back" thread!
Which convinced me that he was the BillW I thought he was!
(seriously, that's exactly what happened.)
It wasn't till after I'd posted that I noticed there were many, many posts already. Including some which looked suspiciously like mine!
Which they were.
THEN I looked at the dates of all those posts.
And you know the rest.
