why cann't I use my yahoo emil in microsoft network especially when enrolling in a competitions?

Question

I wanted to register in love and seek but my yahoo email was regetted by them that i can not use it.

Answer 1

use hotmail or msn

Answer 2

are you sure that you typed the email address in correctly, try it again i dont see why it shouldn't work, if not you will have to set up another email account such as msn or microsoft outlook. My email address always works when signing up to things so it could be a general typing error, hope this helps
