Where is the option to resign from this group? Grrr

Or at least change notification details. Should not have to hunt for this.

I ended up in a wrong group too once. When you hit the notifications icon, to the right is 'manage my notifications. You can disable from that link.

Charles, when you receive an email that there's a new post, you should see this at the bottom of the email:

You're currently following all posts on this discussion. You will not get another email about this discussion until you visit it on Goodreads.

It's a link.
Hope that helps.
