A short note on your email.

• Whether you joined from the English or Chinese page, so we can write to you in that language.
• Whether you have confirmed your address yet.
• When you first signed up, when we last sent you a confirmation link, and when you confirmed.
• Whether our email service accepted the latest confirmation email. If we can’t tell, we don’t send you another until its link expires, because it may still arrive.
• A one-way code made from your confirmation link, and when that link expires, so we can check the link when you open it. The code can’t be turned back into the link. We delete both once you confirm.

To send a link that confirms the address is yours. Confirming is what places you on the list. When Z IS opens, we use it to send you one notice.
