Are we allowed to have mods?

In general, User Interface modifications are acceptable for use in World of Warcraft, Dramuss; however, since they aren’t created by us-Blizzard-we can’t vouch for the permissibility of any given interface in its current version. Similarly, we cannot guarantee functionality nor provide technical support. Just keep in mind that coding to modify the style and look of the UI is allowed, as long as the modifications are done to the sanctioned internal files of the game. However, any UI adjustments that allow the user to gain any sort of an unfair advantage over other players (or any adjustments that are malicious in nature) are unacceptable.
