Currently, there is not automatic categories in the Babel Extension. There are already several automatic categories made with the Babel templates under this main category:
Categoría:Usuarios por idioma
The Babel Extension can use its scheme of subcategories:
Categoría:Usuario es-N
Categoría:Usuario es-0
and so on.
There is community consensus in favor of this:
