If it’s taking really long to heal, you’re going well beyond failure. There’s a heightened risk of injury, but again, that’s not failure.
The bigger issue is that training to failure does less for strength or endurance. It’s more about muscle size. And the benefits are seen if you train to just below failure. Actually crossing that limit is mostly meaningless, as far as your muscles are actuslly concerned.
There are still hiccups with nodeBB’s federation, and it’s not at all clear to me yet that it supports back-fetching forum posts yet. The devs are being super responsive, though, and I think we’ll see the rough edges sanded off quickly.
