Unlocking Kanji Lessons

Hi @harknesd ,
Have you read the Guide and FAQ? @jprspereira 's guide is also incredibly helpful.
If you have, then basically, due to the Spaced Repetition System, once you have reviewed the radicals enough times correctly, and they have reached Guru level, the first Kanji lessons will unlock. It is slow at first, but it will speed up.
If you’re looking for stuff to do while you wait, check out The Ultimate Additional Japanese Resources List!
I hope I have explained it well enough, although people have probably said it better than me in one of the threads here: The collection of threads with similar questions to yours
Happy Wanikaniing : )
