Well, no one got the answer to the football trivia question. Gert came very close, but didn't quite get it. The question was:

In the 1991-92 season there were 11 clubs who had done this.
From 1992 to 1995 there were 8.
From 1995 to 1996 there were 7.
From 1996 to 2002 there were 6.
From 2002 to 2003 there were 5.
From the start of next season there'll be 4.
Who are they and what have they done?

And the answer? Preston North End, Burnley, Stoke City and Notts County have all remained members of the Football League for it's entire existence.

There were twelve original members: Accrington, Aston Villa, Blackburn Rovers, Bolton Wanderers, Burnley, Derby County, Everton, Notts County, Preston North End, Stoke, West Bromwich Albion and Wolves.

Acrrington went out of business and dropped out of the League.
Villa, Blackburn and Everton all resigned from the League to become founder members of the Premiership in 1992
Bolton were promoted to the Premiership (leaving the Football League) in 1995
Derby were promoted in 1996
West Brom were promoted in 2002
Wolves were promoted in 2003

Derby, Bolton and West Brom were all subsequently relegated and rejoined the League, but they weren't members during their time in the Premiership, so don't count for this question.
