WoW-Mania

Hey Guys,
I tried changing the realmlist in the Data enGB file but it does not want to save it up. it says that i can't save it under the same name. anybody know how can i change the realmlist and save it ?

Use realmlist.wtf in your root wow directory and change it with the notepad. Save and relaunch the game. Hope that helps.

I don't see a realmlist anywhere, did I forget to download something?
