Since the Classic guide now is available on the MEMBERS -> Products page
    To install the Classic guide, you now need to be aware that the World of Warcraft folder now has two sub folders “_classic_&_retail“.
    You’ll find the “interface” & “WTF” folders etc. inside those.
    Step 3
    Classic guide goes here:
    Path:World of Warcraft_classic_InterfaceAddOns
    Retail guide goes here:
    Path:World of Warcraft_retail_InterfaceAddOns
    GO GO GO! Have fun :)
