Updated and added the names.
Please note, it was brought to my attention that there was some confusion over the Cryptic Clues event. It seems that my mention of 'cash' prizes made some think that these not only would be real life prizes, but also that Arenanet was sponsoring or otherwise holding the event. Neither of these is the case. What I meant by 'cash' was that it would be straight up in-game gold, not to be confused with gold items. I certainly didn't mean to imply real life cash, though looking back at the original wording I can see why that distinction was such an issue.
I've edited the original post on the forums and also on the wiki to reflect this.
