Multi-language and Community Builder

Sorry, another question...

You had mentioned that you can use

If your fields use language strings, sure. You can use language strings for field titles, descriptions, and many other parameters. You can then use language overrides to translate them in each CB language plugin you've installed as needed.

The question I have now is "How do I use Language strings?" Do I simply input a title (eg: I_HAVE_NO_IDEA_HOW_8786W) and then go to the language plugin and create an override that recognises that language string and then override it this way?

Yep that is litterally what you gotta do:

Yup, just make up a language key. They can be whatever you want. It can also translate strings 1 to 1. Example as follows.

Key: This is my English string
String: This is my Translated string

In the above case I'd specify "This is my English string" and just override it exactly as is. Alternatively you can use language keys. Example as follows.

Key: MY_FIELD_1
String: This is my field

There's not really a set in stone format. What you see in our usages is just generated language keys from the strings done by our language parsing.
