Emma,
I now have two published versions of Fordson. One for 3.2 and one for 3.3 in the repository.
https://moodle.org/plugins/pluginversions.php?plugin=theme_fordson
These are both Fordson version 1.4.3.
I also updated our Moodle sandbox to Moodle 3.3Beta and I am running the latest version of Fordson and Easy Enrollment plugin: http://moodlesandbox.dearbornschools.org/
