I don't know if there has been a thread like this before or not... but I sometimes wonder where the "user" names come from.
So, I'm not too shy to start.
Mine is "billnvick." The "bill" is me, the "vick" is my wife of nearly 36 years. Her name is Vicky, but me and some family members and a few close friends just call her "Vick."
We started using that handle back in the late 90s when we first signed up with eBay, and just found it easy to use it for other purposes as well.
From time to time, if you check out our eBay auctions you'll find stuff (mostly collectibles) that she sells as well as my drum and Star Wars and Star Trek stuff...
