I'm trying to set up alert emails for a blog but am having trouble figuring out how it knows what email to send to. Once I set up SMTP I started getting error messages that I didn't have an email address when I tried to sign up for alerts which made sense since I had never set it anywhere. My initial thought was that I could just go into my profile and find an email field and fill it out. Alas, the contact information does not include an email field (yet hilariously does include a fax field). I've found a way to set a user's email through Central Administration but I want the user to be able to set their own email. Is it possible to have this added as a field in the user's profile under Contact Information that the alerts will be smart enough to use?
