How do you search an email on the new tumblr?

You know how on the old layout you could search an email and it'd come up with the blog that used that email? Can you do that on the new layout?|||when you are in your dashboard click on add or remove under where it says the amount of people that you follow. You will be redirected to a new page and you should find a link that says people you might know. Once you click on that just put in the email address and then you're done.
