General Discussion

Probably Astronaut or newcity.
I have a habit of making my username song titles, hence my current user.

I would just change the spelling from AaliyahMoon to Aaliyah Moon

Jackal. Hands down. I want thst name so bad but 1. I don't want to give up Rexcaliburr and 2. It's on a LOCKED account.

calliope.

Gyrfalcon, or Ceru, which is just the nickname for my current username.

I use this one a lot thanks to Pokemon Showdown, but I would probably change to a banana related username because of family jokes. Also I just like bananas.

If not that, I've been using GhostTricked as a username for other sites. I quite like it.

I'd probably make it a Final Fantasy reference

I've been on the internet long enough that I definitely have 'second choice' names if Dinogrrl happens to already be in use somewhere:

teh-dino
Lex Artis Studios, or some variation thereof (this is what I've named my 'art studio')
Phantom Musketeer (after Dinogrrl, this one's my oldest SN)
Phoenix Rush (though I usually use this one for my OCs)

Among a few others that I use when I want something not easily connected to my 'Dinogrrl' name. But I've had 'Dinogrrl' for so long now that I try to stick with it whenever possible. I answer to it IRL as readily as my given name.

The only username I’ve actually considered changing to is Mithology. So probably that? Familiar-based UNs seem kind of appealing, but I don’t want to leave Orodruin behind.
