Part of me wishes that you too would have a tight time limit. Your level 19 still keeps me up at night. It disturbs my work. It makes me slightly worse as a person.
If you'd like us to lock you out, we can do that for you. :)
Apart from not being able to run the challenges on Firefox, the Matasano CTF has been great. Now, if only I could figure out level 2...
Ah great, ok. I'm really enjoying them, and would really like to finish both!
