I don't think you will see much discussion going on here, so let me be the one and only making an entry...
THIS IS THE HARDEST CHALLENGE I HAVE EVER ENCOUNTERED. Rarely have i put that much on hold in my life, due this Rastaplace. The stuff I have learned so far is not something you will find on the regular HTB machines.
I really urge you guys to come over here and give it a try, it is simply amazing, not sure if I can go back to the regular HTB machines again
