I guess the best way would be to create a page here on Meta, where it can be marked for translation and thus easily translated into many languages. Then it could be copied into different Wikipedias in that languages or the Wikipedias can just link to Meta. --Base (talk) 16:01, 4 June 2016 (UTC)
I'm only active on the English Wikipedia, but this makes sense to me! Funcrunch (talk) 23:10, 16 June 2016 (UTC)
This seems like an excellent idea, which could in addition easily be combined with other ideas, too (such as for example providing access to a help team). Carolin (talk) 15:03, 18 June 2016 (UTC)
