We don't have an exposed way. We'll probably do a summary blog post in the future with stats though!

I would LOVE to see something like a graph with the number of users who are logged in at each level over time and a little log at the bottom.

"User 10.0.0.1 read the level 1 file" "User 10.0.0.1 read the level 3 file"

Then I am a stats junkie

I've been trying to read $ history

Failed. :) I figured that would of been an easy way to progress through the levels. Read bash history from other users.

(This would certainly work if you can read my history: I don't consider the level "complete" until I get it down to a short bash one-liner that prints out the password. ;P)
