Sorry for crossposting. CLDR data submission has started this week, we're looking for more translators: so far I have added 23 new translators who made over a thousands translations and seem happy with the system. Instructions are kept up to date at https://translatewiki.net/wiki/CLDR#Contribute_to_an_existing_locale.
As you know, Wikimedia projects exist in almost 300 languages; supporting them all is a big effort so we partner with other organisations, also via Unicode. One small but visible thing we miss is that many interwiki links in sidebar (among others) don't offer a translation of the language name when hovered. This can be fixed: we're now able to translate 100 more language names in your language.[1]
If you're interested, I can create you an account to submit translations on the CLDR web tool (within June 14): please send an email[2] to ask one and I'll follow up with instructions. On CLDR you can translate and tweak many other things, if you desire; your work will impact hundreds of software projects.[3]
