If you want your publication to disappear automatically after a period, you can set an expiration date for that publication.
How is it done?
1. Go to admin.dink.eu
2. Add a new publication or edit a publication and click the field "Expiration time"
3. Choose expire date and time and click "set"
You will see the expiration time next to the publish time
4. Delete expire date: Click on "Clear"
When expiration date has passed on a publication, the currently live edition is automatically set to "publish for test".
