UBB.threads PHP Forum Software Community Forums UBB.threads Version 7/8 Support Language Editor - new language strings?

I have a question about the Language Editor. At the bottom of each page, there are blank fields to "add new language strings", and I'm not sure what that would be used for.

Can someone give an example of a practical use of adding a KEY and a STRING, and how it'd then be used (specifically)?

Thanks

it'd be used for modifying yoru forums, you can add language strings if you wanted to not have to hardcode them into the forum.

And you'd referance them as you would any language string in a template.
