How do you get people's e-mail addresses?

When I get a email, how do I add peoples email addresses that are in the header of that email.?

• I have Yahoo Classic Email. I remember when I wanted to add someones address from the header of a message there was a button called add addresses. But I have not seen this option in a while. Is there a way I can add email addresses into my address book without typing it in manually?

• Answer:

  If you look next to the e-mail address you should see a small icon that looks somewhat like a file card or something with a green plus sign on it. You should be able to click that.Yahoo! Mail classic was recently updated so perhaps they removed this option. The only other way besides typing them would more than likely be copying and pasting them... I hope this helps
