Stupid daibzzxs! Just because of him we had to change our cool cipher! But he won't be bothering us any longer. Did you see that in the time zone line it says +1372? Apparently he doesn't even live in Estland, so how does he think he can stop us!
Hey! Just because I cracked your code doesn't mean I'm stupid! And my name isn't DAIBZZXS! Use math and it shouldn't be too hard to find out my name. And by the way, I'm a girl. Don't you forget that!
So, looks like you used ATBASH this time. Nice improvement! Did you know that the name ATBASH comes from Hebrew? It is an abbreviation of the Hebrew letters Alef, Taw, Bet, and Shin. Alef is the first letter from the Hebrew alphabet, Taw the last. Bet and Shin are the second and the second to the last letters. So you see that the name already shows how you encrypt and decrypt texts with ATBASH; you substitute A with Z, B with Y, etc.
Anyway, I'm glad you changed your "subject". And next time you write me a letter, it would be kind of you if you used my real name. Or at least take notice of the fact that I'm female ;-).
