How'd you decide on your nickname(on the forums)

I've often used it as my characters names in mmo's (Jubiley if I can't spell it right).
One of my favorite X-men, she shoots out fireworks.
Wow -> I play a Priest -> they gave us penance -> looks like fireworks -> hello, Jubi!
Plus, it means to show great joy or satisfaction...and I consider myself an upbeat person! Happiness makes life worth living and all that jazz.

[Kergeros]

Been using this for years now. It holds a lot of meaning to me. And yes, it's a typo, but I keep it that way. (The correct way would be Kerberos, which is the greek name for the giant three-headed dog that guards the entrance to the underworld. Also the name of a character in Card Captor Sakura.)

[Tyto]

Tytonidae is one of the two broader families of owls(the other being Strigidae). More specifically Tyto subspecies barn owls are identified by distinctly heart shaped faces or "masks" and are often called masked owls. I'm a late night kind of guy with a history of insomnia, so I've been called a nightowl, but I thought "Night Owl" was a little too straight forward for a username, and since the iconic barn owl face makes for a nice, simple, monochrome logo to use as an avatar, "Tyto" I became.
