What is the official stance on graphic modding for ffxi?

[Pixela]

Is it fine to use them according to the ToS, are we allowed to discuss and post them on the official forums?

Talking specifically about editing textures.

Officially? Hell no no no super against TOS. Unofficially though, it's not really something they can get you for short of telling people you're doing it in game. One of the most common things probably is changing the window backgrounds.
