Email firstname.lastname@example.org and ask them. They resurrected all my kanji at once a couple weeks ago.
Oh. Do tell! :) (I'm a LL strategy geek. ) Did you decide to do this because you had burned all the kanji? Is this a massive review?
I'm finding that reading kanji in context is easy but I want to make sure I can recognize all the kanji alone. I start to get confused between similar looking kanji like 直, 値, and 置, or 幾 and 機, etc., even if they're easy to read in context based on the characters around them. I'm doing it mainly to put everything up on the board right next to each other, so I can realize, "Oh, the き in 機会 is just the 幾 in 幾ら with a tree radical on the left." So really it's just to make sure I really know the radicals in each one and can remember the meaning without context.
So, how would that work?
You would get them back as thousands of lessons to be learned?, or would they appear as apprentice and give you a hellish review queue?
How would that appear on your wanikani?
Yes, resetting them sends them all back to apprentice. Now that I think about it, OP might really not want to do this if he or she already has regular reviews to work through. It would be nice if WK had a "never-burn" mode where things just keep coming back at some long interval unless you mess it up. Luckily, Doublevil's Houhou SRS program does have this feature!
