This is true, I regularly use the timestamp on my other sites to future post, but I find it has some shortcomings as well. With macros, your Wordpress installation would automatically put up, take down, update, refresh, or duplicate posts at the interval or specific date you assign. This would be more useful for community oriented websites that have time-sensitive event information, announcements, recurring events, or features like “___ of the week.” Would you find something like this useful?
