I am the real "Henyte" - that is my nickname.
I am owner of "twitch.tv/rank1gg" channel where I usually stream.
I also had/have Henyte nickname on AT/Blackrock realms where I am best known.
This account I write from has "Henyte" char on Blackrock realm so you know who I am.
One guy here on Lordaeron stole my nickname to act as me on this server to harass me.
I can't start playing on Lordaeron without my real nickname.
Could you please recover and change my nickname to "Henyte"?
