Yes, we support having your posts continuously cycle. To have the posts on your wall continuously cycle you'll need to enable it on the Content screen of the wall builder—by default it's already turned on.
When you enable Post Cycling, two more options will appear below, "Cycle Delay Time" and "Cycle Post Limit."
The Cycle Delay Time option is the number of seconds each post will be shown on screen before showing another Post. It defaults to 7 seconds, but can be changed to any amount of time (in seconds).
The Cycle Post Limit option determines the number of most recent posts that we'll continuously cycle. By default it's set to the 25 most recently displayed posts, but can be changed to any number from 2 to 255.
