Contributions page currently lists your existing contributions, but it is a natural place for also starting new ones. By adding an option to create new translations, users that want to contribute will consider translations as an option for doing so.
Designs for the general idea (including different kinds of contributions) are available at https://commons.wikimedia.org/wiki/File:Contributions_redesign.pdf
As a user, I can access to my contributions page when I want to contribute to the project, so that I can create new translations as one of the provided options.
- Provide option to "translate" from contributions page.
- A generic "New contribution" button will provide options to create an article, a translation
- Make this part of the CX beta feature.
