In over 20 years, I've never seen a site use their own custom forum software. I've worked with and have experience of many, PHPBB, Invision Powerboards (now community,) MyBB, Xenforo, SMF and VBulletin, forums modules for wider CMS packages such as wordpress, Drupal, and Joomla, but never an entirely ground up custom forum.
I've coded integrations for linking PHPBB to other CMS packages in the past, so that they both use a combined user database, and that was hard enough 17 years ago. In this day and age It'd be a hell of a lot of work to code your own forum software, and for absolutely no reason, when so many good solutions exist.
We now live in a world where most professionally built websites are built upon existing tools, such as wordpress (which accounts for 43% of all sites) amongst others, so no sense in coding an entirely new forum software package.
Neil has done a good job with the software side of the site in my opinion, a very good job, it's simple, fast and reliable and is amongst the best user experiences of anything I've ever seen of this kind. It would be easy for the new owner to go changing things, adding plugins for this and new integrations for that, but that could impact the overall user experience negatively. Last time I had to do it, Facebook and Instagram for example, required you to set up an app on their side that talks to their API, in order to enable simple embedding.
Wildly off topic though, sorry about that, as for Trump, I have nothing really positive to add to the conversation. I do hope that he can open up more dialogue on a Ukraine solution.

I had to google what a BRICS nation was... Quite the blunder already. 😕
