The idea of "confirming" kintypes is so strange to me. How would one "confirm" a kintype? Hell, I've identified as a wolf for literal years and it's an integral part of myself, but that doesn't stop me sometimes wondering if I really am a wolf (the doubts don't last long, but... with no objective way to know for sure, it seems natural to occasionally stop and wonder if I am what I think I am). I wouldn't say I'd "confirmed" any of my kintypes, because that implies that I've found some way to objectively verify them, right? And I haven't.
What does "confirming" even mean in this context? How would one "confirm" their non-physical identity? (Rhetorical question, but. At the same time I'd be interested to know how people who have "confirmed" a kintype actually went about that).
Whatever you were trying to write, I recommend writing it on a word doc the second time around and then just copy and paste it. That way you can actually save you progress.
