I think FliteTest prioritizes Facebook because of the much larger potential audience, so they’ve probably decided not to spend money on maintaining the old forums.
If that’s the case, I understand the business case for it, but it would be a loss if the forums went away. They’re such a good resource. Information that goes into Facebook just disappears. It’s not searchable on Google, and even if you go to Facebook to search for it, it’s difficult to find because Facebook makes it intentionally difficult to find things in order to hold your attention for longer.
FliteTest, I hope you’ll consider keeping the forums on life support. ❤️
