ltg?
Fragment of a discussion from User talk:Dark Eagle
OK, that sounds sane. Dark Eagle, please be aware that if you go through with this, we will (a) not add ltg to MediaWiki proper before ISO gives out the language code (b) if ISO does not give out the language code, support for the code will be withdrawn, (c) for now you are only allowed to work on MediaWiki core (message group "core") in here for code 'ltg'. Of course, feel free to work on anything else for the languages that are recognised by ISO that you are proficient in.
OK? If so, please provide me with an autonym for 'ltg' (the name of the language in the language itself). I assume it has to fall back to Latvian ('lv'). If otherwise, also please let me know.
