(at the moment this post will be incredibly sketchy until I can research who actually broke each code, any help is appreciated)
Sweeps winners (premiere):
Sweeps winners (posters): OogieBoogie & bfunk00
Code 1: Didn't need to be broken. Anyone with eyes could figure it out.
Code 3: As far as I know, this was all on Pikachuchu.
Code 4: Jason S let me know - I don't know if he was first or not.
Code 5: Padraic & Mycroft
Code 6: Laurabelle & Peshmode, and Alison (who was on the right track, whether she knew it or not).
Code 7: Truffula
Code 8: I'm gonna say liam, since he pointed out the frame as soon as we got that video.
Code 9: Me! (although I'm open to contests against this).
Code 10: Zero
PANATROG Passphrase: butterchik
Disclaimer: like thebruce says, there may have been people who cracked the codes before all of these guys, who perhaps weren't posting on HETFET - in which case this is a list of people who were first to report that they'd cracked it. Not that that should make you all feel any less proud of yourselves :)
