I have just started using this plugin.
All fresh install of WordPress multisite.
Main site (top dir) is in Spanish, and /fr/ is French in a subfolder.
I presume this is supported fine - using the main site as one of the languages?
Also: the switcher plugin says that the language modules must be installed. Does a language module make the admin pages also use that language? I don't want the wordpress admin and settings controls to be in different languages - only want content (posts and categories) in Spanish and French, while all logged in activity needs to be English. Is this doable using the multi-language switcher?
