Very simple! Just post one letter for every comment, and make sure it is Capitalized like this : A, B, C. The rules are one letter per comment, and once you finish A-Z, you start again, like this: AA, AB, AC, and once you reach AZ, you move on to BA, BB, BC... BZ, CA, CB... CZ, DA! Like that! The Main Goal is to get all the way to ZZ! Good Luck! Also, you can post as many letters as you can in a row, but 1 Letter per comment, and Capitalized, and in order pls!
