I heard about the NPL in 1981 at the Stamford crossword tournament, from Ditto, Zonker, Treesong and Sluggo (I think).

En is an old family nickname. Instead of the usual Ellie or even El, my sister and parents called (and still call) me En.
I even have Mickey Mouse ears with En embroidered on the back.
My nickname is N.
When I got online, I was not allowed to use a 2-letter nickname, hence Ennie.
