Collaborative internationalization platform is ready to publish translations in
bitshares.org, you can test its' behavior by switching to Spanish (translation in progress, I'm doing it myself when I have time).
https://www.transifex.com/bitshares/bitshares-org/live/ is open for everyone to translate but you have to create a free account (or login with github or gmail) to use the Live feature, which we are using to translate bitshares.org.
bitshares-org is bitshares.org project. We can add as many projects as needed if they are open source.
I'll add graphene-ui internationalization project soon.
Feel free to ask me to add more languages and for user permissions. Available roles are Translator, Reviewer, Language Coordinator, Team manager, Project Maintainer and Organization Administrator (I gave admin to Cass and xeroc so far).
Translations needs Reviewer (or higher role) approval to get published, so anyone can just start translating.
