I use very restrictive spam filters for email, so the only way you can count on being able to send email to me is if you register your email address(es) with me here so that I can put you on my whitelist of current students.
Also, I regularly send email messages to my students to make announcements or correct mistakes that I make in class. I use this same whitelist as my mailing list for these announcements, so it’s doubly important for you to register your email here.
You may register multiple addresses; just complete this form for each address you want to register.
If you want to drop an email address from my whitelist and mailing list, just send me an email message telling me what address to drop.
