to prevent mail dellivery delays:

from our helpdesk: "...couldnt find your email ? maybe you registered wrong? Found Doesnt help for better delivery if lots of people use wrong emails as the email provider then will block delivery if too many sent mails are wrong. That is to protect themselves from Spam what is ok. So if you like the service, register with a WORKING email ? receive mail, click link. Enjoy service. Tell all your friends that in this way it will work much smoother to all. :)"
