Is that the same gig for which you joined a team awhile back? I had checked out a few puzzles (prior contest), but they were too hard for me. I can understand why teams of detectives form; solving requires hunting for breadcrumbs!
No I think I might have been referring to the Mezzacotta Puzzles originally called CISRA (I think). This is a different group but similar sort of puzzles. I love them and they are great to do in a team - two heads and all that. Getting the starting point is often the hardest bit.
