I've noticed here on the Moodle.org website that when clicking on the forums for different languages, the title-bars and menus also change language.
What do I need to do to change the default language for a forum and various pages in my own instance of Moodle?
When you look at forums for different languages on moodle.org you look at forums in different 'courses'. In each course you can specify the default language in the course settings, just choose among the installed language packs on your site.
thank you gentlemen. This is what I needed. I'm enjoying getting to know Moodle.
