1. You have the link to the User Interface Customization tool as: www.blizzard.com/support/wow/?id=aww0167p

     

    This is not working for me.

    I believe Blizzard's servers are having problems this morning. Try again later. An alternative URL if that still doesn't work is http://www.worldofwarcraft.com/ui/ (which also doesn't work at the time of this posting).

    The site seems to be working again, albeit rather slowly.
