In order to change it all you have to do is when you log in go to "your account" and under "community moniker" you just change it and put "-=SoW=-" in front of whatever name you want displayed. The change is free and all you have to do afterwards is type in your password to confirm it.
A few things to note:
The change is free and can be done as many times as possible
Be sure to use the minus "-" at the beginning and the end
Put a space between the "=" and the letters
Below is a picture of where the community moniker is located and how it should look:
Thank you and any questions feel free to ask me or any of your guild leaders for assistance.
