i had 8000+ points on hts... decided to do an IRC challenge and lost all of my points. im not down to 10 it still displays that i've completed all the challenges that i've completed thus far on hts, yet my points are not reflected here. possibly the IRC challenges in hackthissite are overwriting the score thats submitted here? no clue. any ideas?
