There has been some issues recently with verification emails that are outside of my control. Do not hesitate to contact me using the contact email address that you can find on the footer of this page (Contact us) or on facebook/twitter. If you state the username and email address used to create the account, I will manually verify it.
It looks like a lot of education establishments have also recently changed their policy. I have a huge amount of verification emails being bounced back to me due to the fact that only emails from a white list are accepted. Using a non education email address may help as well.
