I signed up for the following services: 1. Mailchimp (mailing list); 2. Disqus (comments); 3. Wordpress.com (adds several premium features to your website). You should have a few emails in your seewaldsmail@gmail.com account. I had to use my email address to sign up for most of the services. All you need to do is click on the confirmation link in the email to change the address.
