I'm trying to crack a code for the Murloc Pet codes, I know it may not be possible but I want everyone who has an expired code to post theirs here. If I find a way to generate a code or if I find a common pattern I'll share. Also, try working on this with me, if you find any patterns post them here. I'm not sure it can be done, but it's still worth a try.
Note: I won't be working on this everyday, just when I have nothing better to do.
