Hi guys,
we are developing a platform at https://translate.foe-services.de for “Social Translation”. It is still in development (you can contribute at GitHub, just have a look) but stable enough for production.
The project HTTPS Updates is already set up: https://translate.foe-services.de/projects/https-updates – As soon as the functions are implemented you will get full access to your project.
If you would like to help promote it you could add a link to the plugin description.
Thx,
Christian
