OK, I’m a little confused, and I’m sorry for confusing you guys. What exactly goes on in the 20414 zip code?
What goes on in 20414 stays in 20414.
Since there are three consecutive incidences of “18”, could that letter stand for W? As in “www” dot something?
That is entirely possible! 
Yes, I know, I’m reanimating the dead here, but…
Can we finally figure this thing out? Or barring that, can we get an answer from tdn?

Assuming 18 = W then it is not a caesar substitution or else we get
wwwhmsimqeglwhooiwnc???
In fact, it’s not a caesar substitution for any starting value
10=T
4=O
9=N
gives “town” befort the “com” “org” “gov” or whatever ends the url.
If so, then 3 represents a vowel that starts off the name of the town.
You most certainly cannot get an answer from me. Mostly because I forgot about this entirely. I don’t know what I was smoking when I made this up. Probably pot. 
It is definitley a URL, but I don’t remember to what. Probably a picture of a kitty or something.
18 = W, but I don’t remember why. Let’s look at the most used letters of the alphabet.
I’m sure I didn’t get it from Yahoo Answers, but just now from there I got
E 12.51%
T 9.25
A 8.04
O 7.60
I 7.26
N 7.09
S 6.54
R 6.12
H 5.49
L 4.14
D 3.99
C 3.06
U 2.71
M 2.53
F 2.30
P 2.00
G 1.96
W 1.92
Y 1.73
B 1.54
V 0.99
K 0.67
X 0.19
J 0.16
Q 0.11
Z 0.09
And W is the 18th letter.
ARFORYC_TSWALLOWH?
I do remember that “swallow” was in it. Did it have to do with birds?
I think I got it
Africa and Europe
Using a slightly different list I got
wwwarmoryc-tswallowh which may mean this.
I think you’re right! That sounds like something I would link to.
Is it 14 k of g in a fpd?
An African 14 k of g in a fpd or a European 14 k of g in a fpd?
Ok, glad we got this one cleared up.
Hey, maybe if someone bumps the 14 k of g thread, the OP will finally come back an answer it now!
Can’t

For Pete’s sake, it’s “14 karats of gold in a Florentine peitra dura.”
