What good online/Web services for translating software do you know?
Please give a list.
Such a web service enable contributors to help translating a software in the Web. The maintainers of the software to be translated will then pull the translations from the web service when they need them.
There is only one criteria I have: The web service should not force users (i.e. the translators) to execute any proprietary JavaScript or other proprietary client code.
It's OK if the source code of web service itself (server-side) is not published, as it doesn't threaten the freedom of the users.
