I hope I don't come off as too aggressive, but site coders aren't magicians.
PHP is not Python etc and while there are existing forum applications already written in Django it'd be more ideal for us to work with the existing models we have on the website than to retrofit another forum app onto the site and pray that it works, then hassle to convert model storage when we need to tweak it.
(It's not even that hard to make a forum: you'd need a backing database and two controllers: a topic controller and a post controller, that pull all of the weight. Bonus points for using ElasticSearch to index it. Only hard thing is a suitable frontend.)
