[chx]

Not trans but I identify with the letters "chx" much more strongly than my real name. There are thousands, perhaps ten of thousands of people out there who know me by this nick and nothing else. My own brother often calls me that. British Columbia doesn't allow me to take a single word as a legal name but once I get citizenship I am very seriously considering changing my legal name to a name where the abbreviation makes it a sort of retronym. (Charles Harry Xavier?)

How is it pronounced? "chix"? or spelled out C.H.X?

[chx]

I heard both :) not to mention the Hungarian pronunciation of c-h-x where I originally come from -- I am using this nick for more than twenty years and 1993-2005 I heard it only in Hungarian as my contact with the Western world was mostly virtual. Then everything changed at the first DrupalCon in Antwerp but I am getting off topic here.

That is a more fantastic answer than I thought i'd get! Even the pronunciation doesn't adhere to traditional name conventions :-)

I love it, good luck.
