Site default language

[Carlos]

- Wouldn't it be better (to be consistent with the rest of configurable options) to define it as a php constant?

Not in GS 3.0, as it is overwritten with the language of the backend user.
But in a new GS version it would make sense to have a constant and use it to initialize the variable $LANG

Yeah... This last question was more of a suggestion, for a future GS release.

Thanks for you answers.
