"Sprite" is an odd name, is that how things are signed by you?

thanks,

I've been using that name for a long time in open source communities, 
here's my GitHub profile:

https://github.com/SpriteOvO

Linux has allowed pseudonymous contributions since earlier this year, 
does this apply to me? If you are concerned that "Sprite" will cause 
confusion, I can use "Asuna", which is the name I used on IM chats and 
social media platforms.

I apologize for the confusion.

A "unique" identifier that you use to identify yourself is fine,
"Sprite" is not really unique :)

thanks,
