I have got email salesforce certification team to connect trailhead and weassessor accounts with a link. I have submitted my trailhead email address. But I didn't get confirmation/verification code to connect the same. I have raised a case with salesforce certification as well. Still no response. Does anyone faced this same issue?
I have followed the steps described here. http://certification.force.com/pkb/articles/Public_KB/Link-Your-Trailhead-and-Webassessor-Accounts
