hacker.org

Hallo all,

i am not a hacker or a programmer. Because of that , i have some problems with the challenges. I have to get a feeling, about to complete the challenges. So i need help for the challenge Challenge 'Invisible Ink' [Web].

Is there anybody who can give me some tips for that challenge?

Thanks

no programming or web knowledge needed on this challenge. Can be solved very very easily. Just have to figure out how

But you still have to think as a hacker - this is "hacker.org" challenges , not "mensa.org" .
