Finally I found the time to rewrite this WordPress plugin to be more inline with the most recent standards and cleaning.
As every release I ask for help on improving the terms list: https://github.com/mdn/wp-promote-mdn/issues/92
The code is quite finished (after porting and got Travis with new unit tests working I have to cleanup and optimize).
For who is wondering about the feature of 2.0.0:
- Removed the box to sent an email to Mozilla
- Widget simplified
- Better UI for settings
- Shortcode for mozilla newsletter
