When you extracted the file, go to your WTF folder-> your account folder and put the content of folder named "Content goes SavedVariables of your acount" into folder named "SavedVariables"
Then go again to WTF folder->your Account-> your Server-> Yourcharacter folder and put the files of folder named: "Content goes into saved variables of you Character" into folder named : "SavedVariables"
And Ofc put the PowerAuras folder into your Interface/Addons folder
You need to do this because addon has a configuration/auras available equaly for every character you have ( account saved variables) and some character specific ( char saved variables).
Any constructive critics welcome. Druid setup will be published soon also (tank/heal/kitty)
