These two work:
gmx18bcj
XIGZ2Y10S2
And a bitchy observation to start the morning:
It kind of bites that, when I got off work yesterday, every code except 1 had been found. Then I look for that 1 (unsuccessfully) pretty much all evening and most of the night. Then I go to sleep for about 4 hours, and when I wake up, two more have been released and both have been found.
This code thing isn’t as cool as the first act was, but I’m hangin in. Hope it’s just a lull.
