I've added everyone I could find a code for in the thread. I might be missing a few from the list, but otherwise I think I got everyone. If you've added me, but I haven't added you just PM me or post here and I'll add you. Here is the list of people I have on my system that haven't added me:
FaintDeftone
Mars10
botticus
jer7583
SinOfHeart
pmm317
bmachine
Batcave
HammerOfGod
pjarvi

unkleEL
Entropy
JaredStorm

Merboy007
These names are from my 3DS so they may be shortened or your XBL tag or something, but I think it should describe everyone well enough.
