This board is a place for comments and suggestions about the website outside of the message board. If you found a typo, or a lesson that doesn't make sense, or you have an idea for a new lesson, this is the place for it!

Alternatively, you can contact me at if you'd rather (for business inquiries, link requests, threats of violence, etc). However, I cannot respond to requests for math help sent to that address. Trust me, this forum is a much faster way to get your math questions answered.
