Very cool. I'm torn on the strict requirements to be listed as a tutor. On the one hand I totally understand the need to filter for quality, and if you still have enough tutors, you've probably set the bar at the right place. On the other hand I am a graduate student and a Teaching Assistant and enjoy helping people learn, although it's not something I'm pursuing professionally.

Small bug: the last two questions in the FAQ under the For Parents And Students section are duplicates.
