Hi, I just now saw the message you sent me on translatewiki.net regarding the messages for gom not working on the Babel extension. I never noticed this anomaly, but you're right, I can never see gom messages regardless of whether I use the code gom or gom-latn or gom-deva. Even the examples that you said worked for you, don't work for me. And not just on gomwiki, but also on enwiki and on translatewiki. Did you learn any more about this?

I haven't looked into it any further. But I see that the gom-latn-0 and gom-deva-0 messages are no longer working properly. What changed? Try fiddling with the local system messages until you find something that works.
