Thanks, @Moin, the thing is, for example, Albanian (24% completed) and Serbian (13% completed) are both available in the interface.
It could be great to merge on the go so that to motivate volunteers translators as they can see the results happening.
Just for context, @Mahuton and I are working on https://forum.movement-strategy.org/ where we are growing a truly multilingual community. If it helps, we can help assess the quality of existing translations still not committed to Discourse. We have staff or volunteers who are native speakers of these languages and we trust their feedback.
