We now have a new (and improved!) website.
The previous website was slated to be upgraded, but along the way it ended up being easier to just replace it as the upgrade path from its previous home under Drupal 8 to its new home under Drupal 9 was not as smooth and well-orchestrated as one would have hoped. As there wasn't much in the old site to carry forward anyway, and as it had been carried forward from Drupal 6 and 7 previously, it seemed a good time to start with a clean slate.
There are many changes that are coming to the website now that this new foundation has been laid. Details to follow as the changes are rolled out.
