On Saturday, the agents were notified that they each had a contact person somewhere at the convention (Ambassador Mollari, Kickass the Klingon, Kerr Avon and the Andorian representative.) All they had to do was to solve a puzzle (on Yellow paper) which would give them the password which they needed to relay to their contact.
Upon completing this task, they received a further puzzle (on Green paper), and a message that the next update would be noon on Sunday.
The Yellow and Green puzzles may be found here (along with the final Purple puzzle) (PDF file approx. 250kb)
[Saturday progress: The Stargate agents had got lost in a wormhole somewhere. The Rangers and Starfleet Intelligence both cracked the What Will You Say puzzle, found their contact and got the green puzzle. They also both cracked the sudoku picture puzzle. The Torchwood agent failed to find their assigned contact - there were far too many “Avon”'s wandering around! - but gained access to the Green puzzle through the Rangers.]
