Novice premium user with a few problems/issues

Hello! I’ve been on this site since its inception. This morning I decided join with a premium membership. I entered my regular email but then saw the discount for educators so I went back and entered my .edu email. My account is still showing my regular email, not the .edu. How can I change this?

Also, where is the swag shop? And wasn’t there a place to adopt words? Is there a map to the site I am missing.

Thanks in advance for any help.

Howdy. I just signed up today. I noticed a merch link at the bottom of one of the home pages:

Hope that helps.
