Some Heisig keywords have only subtle differences and you have to create your mnemonics carefully so that you don't mix those up. I want to revise some of my mnemonics and clear some things up, so I started to put a list together with keywords close to each other. If you have any suggestions to add to the list, just post it and I will add it, since we can edit posts now...one problem is that I don't know the pronunciation of many characters so I can't type those to input into Skritter...maybe someone already learned the pronunciations and can add the characters?
