This is a post that is all in the title. As I done a code post,I am going to do another.I come to do it,if it has 1,3,5,7,9 and other odd numbers of letters you just use the letter in the middle.If it is a even number of letters, there is 2 [two] middle letters[midletters].Use the 2nd [second] middle letter[midletter].If it has 1 letter, delete the letter.You can use it for 100000000000000000000000000000000000000000000000000000000000000000000000..........[google]letters.BYE.
