Hi,

I really enjoy Khan Academy and this site has helped build up my foundation in math to get me through some of the college classes. For many reasons that is something that high school couldn't provide for me. Altough Khan Acedemy have lot's of material on combinations, permutations and other Discrete Math related material, I feel that it lack Discrete Math as a subject. Searching through youtube I stumbled upon the channel TheTrevTutor that is very good teacher in Discrete Math. He is also on the site trevtutor.com. I would really love to see him teaching here at Khan Academy. So this is my recommendation letter :)
