You can do all that and more at http://www.eogn.com/amember/member.php. You then will need to enter the user name and password you created when you subscribed. If you have forgotten your user name or password, there is an option on the same page (http://www.eogn.com/amember/member.php) to have them sent to you in email.
Once you are logged in at http://www.eogn.com/amember/member.php, you will see exactly the same information that I see. The only difference is that you will only see information about your subscription. When I log in with my system administrator's user name and password, I can see everyone's subscription information. Otherwise, you will see exactly what I see. You can see the expiration date and you can change your email address, your password, or even your user name.
You can also renew your subscription at the same place: http://www.eogn.com/amember/member.php
