Why do I not receive my email updates?
Email updates are sent once every 24 hours to prevent you being bombarded by emails if your friend updates 5 times in one day! If you still do not receive emails a day after you know that a page has been updated then the probability is that the alert was sent but was identified as spam by your email provider. Unfortunatly, because we send so many emails everyday, it is easy for an ISP to mistake our alerts as spam.
