title: Get email ID of user in SPServices
body: <p>I am using SPServices (GetListItems method) to fetch some information from a sharepoint list. The list contains a "People or Group" type field which returns a numeric id and name(Display name) of the user separated by semi-colon like this "43#;John Doe".
  I need the email addresses of all the users in this field (in all the rows returned). Can anyone help?
  Thanks in advance.</p>
