1. Take your LJ username and replace each letter with the corresponding number (A=1, B=2, etc...).
d = 4
e = 5
a = 1
t = 20
h = 8
b = 2
y = 25
y = 25
u = 21
r = 18
k = 11
i = 9
s = 19
s = 19
2. Add all of the numbers together to create a kind of super number.
super number = 187
3. Add the digits of the number together.
digits = 16
4. Find the post of this number (step 2) in your LJ. If you don't have that many posts, add the digits together.
(1+8+7=16) Entry 16
5. Take the digit you noted in step 3 and the digits together, and count that many words into the post.
words (1+6=7) -- "when".
6. Use the resulting word in a google image search, and select a picture from the first page and post the results.
