Thanks for stopping by, John! Anyone who's seen your work on other crypto sites knows you're capable of doing the much tougher puzzles, so I look forward to seeing you take a shot at some of the more challenging ones, too.

For those who are new to cryptograms, note that the key to the atbash cipher is:

p: ABCDEFGHIJKLMNOPQRSTUVWXYZ
c: ZYXWVUTSRQPONMLKJIHGFEDCBA

In other words, we can say that plaintext A equals ciphertext Z and vice versa:

A=Z
B=Y
C=X
D=W
E=V
F=U
G=T
H=S
I=R
J=Q
K=P
L=O
M=N

I found this cipher very interesting! It prompted me to do more research on "atbash."
