Is it possible to adopt an orphaned plugin so as to bring it up to date with Moodle if the maintainer is no longer available? I have no way to reach the developer through Moodle, and the person whom he originally wrote the plugin for is unable to contact him. I reviewed the documentation at https://docs.moodle.org/dev/Plugins_adoption_programme, but he's no longer even logging into Moodle. I'm just bringing it up to Moodle 3 coding guidelines and PHP 7 standards, there are very few people who use it according to the stats, but I'd like to help anyone else who does. What's my next step?
