A mod to alter or remove zoning text?

[Tacitus]

So, whenever I walk into Orgrimmar or such, there's the "ORGRIMMAR - Horde Territory" text in the middle of the screen, as well as the "Discovered: Orgrimmar" text if I've been there before. What I was wondering is: is there a mod that will change how that text is displayed, or remove it altogether? Heck, is such a thing even possible? I've been looking throughout various mod sites for "Zone text" and "Area text" and stuff like that, but I don't even know what those messages are called.

Does anyone know?
