When the passwordconfirmation field is typed, I want not only to tell the user if password and passwordconfirmation are equal, but also tell the user if the email is in database. Right now, I am thinking about echoing one responseText with a separator (the vertical bar). I am thinking about data like "| || | || | || | | || | || |" happening next. What are the alternatives to a separator? For example, is there a way to echo an array???
