I know I am subscribed, so why can't I login to the Google Group?
As a member of the list, you should be able to interact with it using email. If you want to be able to login to Google and browse the list as a forum, then you need to have a Google email address (such as Gmail) associated with the list. Without a Google email address connected to the group, you will NOT be able to login to Google and see the group. This is something Google controls, not IECA.
