Don't worry, we are not going to SPAM you. We hate SPAM too.
Q: Why do you want my email?
A: We use it for validation purposes to see if our products are being viewed and is helpful to anyone. We will send occassional emails when we run across new resources that we think would be helpful to students, most likely at a rate of once a month or less. We are not going to SPAM and you can unsubscribe anytime.
