Stacks allows users to associate an expiration date and other publishing attributes for most content types. Setting an expiration date allows you to schedule the removal of content; this can be particularly helpful when planning seasonal or time-sensitive content. Eg. Schedule "Back to School" themed content to expire on October 1st, or for content related to a program to expire once the program is complete.
Depending on the user’s role, they may have the option to also choose whether to publish the content immediately and/or to ensure the content “sticks” to the top of any list.
