ATA purchased a new forum host, several weeks ago. It gave not only a UI update, but a functionality update as well.
If you search "Getting Started in Forums," you'll find @Kefo 's excellent guide on how to navigate the new forums. Search by clicking the magnifying glass in the top left corner of the forums main page.
This is horrible in my opinion, the old one was perfectly fine. This isn’t mobile friendly at all, this looks like a normal web browser squeezed into the app. Just because KoH uses XenForo doesn’t mean PIMD should too, does KaW have this update too?
