Well, what have I started here!
Since I started this thread I've had computer problems, and have only just got back on line. Rather reminds me of the time when I was a student when I left a box of coloured chalks in the Gentlemen's Loo (no nickname for that required here...). I had borrowed the chalks from a school I was doing some teaching practice in, and I'd noticed there was a blackboard for graffiti in the men's WC...
When I came back twenty minutes later, ALL the walls were completely covered in unrepeatable comments...
Anyway, just read a book about the history of Norwich, and their inhabitants are sometimes referred to as Norvicians (apparently....)

N.B. The example that got me started in the first place here was: "Taswegian" for someone from Tasmania, by the way.
