I’ve explained this in similar threads before.
I knew my hubby was a geek before I married him, but I am not, and have never been, a geek. Because he was one, though, we had the internet before just about any of my family/acquaintances even knew what the internet was! ("The internet?!?! What do you want that for?!?) Somehow, explaining that it allowed me to ‘look up’ Ebert’s movie reviews didn’t carry a lot of weight. . .
Anyhow. . .back in the day (as we old folk say), when you got the internet, and hence an ISP, you got an email addy to go along with it. My email addy was my first name plus my last initial, but all lower-case: norinew. So that’s what I had. So I used that as my username everywhere I joined. Just so happens the SDMB was the first message board I ever joined.
It never occurred to me that people would read the name as “nori-new” until people started referring to me as “nori”. At that point I thought "Hey, they think I’m nori-new, not norine w. Hmmm. Well, I could change it. But to what? Nothing sprang to mind.
By now, it’s gotten to a point where I think of myself as “nori-new”.
