I've been playing around with the Campaign module in Sugar 5, and I have been unable to create a tracker for which the user can choose to opt out of all future mass emails. I see in the removeme.php file that this is supported, but I don't quite understand what needs to be done for this functionality to be triggered. It seems to me that the opt out trackers I create only ever opts out of the campaign, which means that the customer will still receive emails from other campaigns later.

Is there any easy way to provide a 'complete' opt out link to enable the targets to opt out of all future mass emails?
