It's interesting that we are both Christopher, and that we both eschew usernames starting with c. That's how I recalled who you were in your comment.

I went with x because Xmas. And because Christopher is such a common name I wanted something different.

I wonder why you went with v, another uncommon letter.

I was 12 and needed a nickname to play counter strike. I thought about “jeux video” (video games in French) -> “video jeux” -> “vjeux”
