yeah, if you really want to change it to 'Atrtemisa' then I vote yes for you, but lots of people know you now (including myself) as blizzard paws, and have added you as a friend, if they don't know you've changed names and are sweeping through their friends list one day and see you they might go 'huh?" and delete you, so yah, as everyone else said, at least make your new name known so people still know who you are when they see you ;D

I was thinking the same thing when I changed my username from Malwolsky. But as Draco said, just change it if you don't like the name. Then you can say you changed your name on your profile, or say so in the shout boxes. It'll be ok.

But some advice: make sure the username you select will be long term. Try to avoid selecting names you're only going to like for a few months. Then you won't have to go through this again XD everybody wins!

If you want to change it, just change it. Maybe just add a note in your profile, or set something in your 'pack/group' text so your can be recognized. Another thing is if you wanted, PM the people you want to know who you are. Then, other than those, you could make a fanart, or image too about it.
