Mine is after the movement in the Requiem Mass, "Rex Tremendę."

Years ago, in another forum, my previous online identity was giving off an impression that did not suit me, so I cast about for a new moniker. A friend of mine found hers in liturgical music, so I looked there too and decided "Rex Tremendę" would make a good name: it came from music - specifically choral music, which I love - and it more or less fit my personality. People of a certain ilk usually recognize it often starts some interesting conversations.

Sometimes people tell me "Rex Tremende" is spelled wrong. Well, yes and no. The first time I tried to set up a profile with this name, I attempted to use the character ę, but it kept changing it to an e. By accident, I committed to the e and not the usual two-letter combination, ae. I decided that "Tremende" looked like a decent enough surname that I should keep it that way.

I have opined as Rex in many forums for so many years that I answer to "Rex" in public as I would to my given name. Indeed, some people only know me that way, and I no longer think of it as just a nom de plume.

Regards,
Rex.
