Oh, I see. Well, I can't change back to my old name either which is poopy.
Since I seem to have to post my response on your page: No, my username was originally Coeruleum and when I changed it and it wouldn't let me change it back without asking administrators to change it I just went with Coeruleum Blue.
Did you choose "Coeruleum Blue" instead of "Azure"/"Azure Blue" because of the rhythmic structure, and the fact that it is more poetic and rolls off the tongue easier?
