I've recently switched jobs, and am having trouble getting my Trailhead badges associated with my new Success community profile.  I use social sign on to access Trailhead now, and am not sure what email address is associated with the Trailhead account.  (Though I have reason to think it's an email address from a previous employer, to which I no longer have access.) . There does not seem to be any way through the Trailhead profile UI to see or change the associated email address.

I was instructed by a Salesforce Help & Training agent to post this issue here, and that someone from the Trailhead team would be able to help me.

Thanks,

Matthew
