Writing 1: email addresses

If you didn't receive an email from me on Saturday, probably I don't have your correct email address. Please email it to me (put Writing 1 in the subject). It's also possible that I have your email address but I get error messages when I try to send you emails (e.g. Ayumi F.). For these people, if possible you should give me an alternative address (e.g. GMail, Yahoo Mail, University email, etc.), or ask a friend to always tell you when they receive a message from me.
