I've set a ton of records on the new puzzles and never seen a name. I also suspect Guest is for an unregistered users. I also think there are an enormous number of different puzzles when you consider that different orders of the same clues create different puzzles for each set of clues. Perhaps all those Guest best times means they have finally fixed the records problem that I think they've had since I started. That or there are so many puzzles that you rarely see the same puzzle twice. Admin could clue us in on this....
