You may create several alerts that all relate to a certain issue. Some of the alerts may be traditional action alerts, while others may be vote alerts or call alerts.
You can create an Issue tracking page for your users to help them keep track of their progress on all the various alerts that you have associated with a specific issue.
By placing the Advocacy Alert List and the Alerts Not Taken components on one page, you can show your users both the alerts for an issue that they have not yet taken, as well as the alerts that they have already completed. If you then provide a link to this Issue Tracking page from each of your alert thank-you pages, you can keep your users 'in the loop' making it easy for them to move on to the next related alert.
