And I don't, but every once in awhile I put a comment about an Editorial - then after a week I am still getting emails about it and it is 4 pages back in my unsubscribe list so I can't fid it to turn off the emails.

Ideally, if the email with the links passed the topic ID back in the URL and the subscriptions list sorted that one to the top, I would be in great shape, but a select all option seems more reasonable. There is already a checkbox next to the "Update Selected" button that appears to do nothing - a bit of Javascript should be able to select all from this one.
