I want to change mine. I was supposed to type Lady_Arthemis. But it dropped off the "_Arthemis"

Is it possible to change/edit it?:o

I'm sure this is covered in the guides somewhere, but here's a link to the announcement about the username change system update.

Since Kinmotsu has answered your question I'll be locking this up. If you have further questions just send me a pm and I can either answer them or unlock the thread. (:
