Excelent website, but:
Problem Solving statistics:
Last 7 days: 1434 solved, 1833 unsolved, 43% solved.
I think It needs more tutors.
As a tutor, I usually directs my students to go to MathTV - Videos By Topic . It's like a youtube but for math problems. Its great because you have 3 different people explaining the same problem and there is even a spanish instructor. All the problems are listed in a very organized manner and recommmend this site to the forums.
