I have 3 languages, and I fiddle around a lot in language files because of some modifications.

I also use 3rd party language files and had no real way of checking if they were complete.

So voila, tool

Download the zip, put the checklanguages.php file in your /forum/admin directory and call it with:

http://www.yourforum.com/ubb/admin/checklanguages.php

It will compare all your languages to the default language, and report any missing keys. Optionally, you can choose to copy every missing item over from your default language to the other languages.

Very nice Yarp
