Stage 3 hints
The third stage is a more complex list, which means you have some clues to follow to find it.
The first clue is the background picture. Download it and then use the link suggested in my "solving puzzles" section to find out what the picture is called. The Greek chap is the person you want. Make an adjective from his name.
The title is also a clue. Think of the sign for positive and think of grammar rather than stress for the second part. That should give you a word.
The third clue is the theme running through the caches so far.
Google one or more of these and you should find a list of numbers. I tell you that you need all your fingers and thumbs, and that is my way of saying 10 is the base your require.
