In short, schedules repeating posts for future publishing.
Allows admins to take an existing post (aka template), and create clones of it for future publication. This is helpful for mass communication blogs which have recurring events or regularly scheduled announcements.
For example, a book club blog could have a post titled – "Team Leaders' Monthly Meeting". In just one click, the admin could schedule a clone of that post to run every 30 days from January through December.
After installing, find your post template, click on edit and scroll to the very bottom of the edit post page to find Repeating Post.
