publish up and publish down

Please explain what publish up and publish down are, when they get set and how they are used.

Hi

Publish Up and Publish Down is only used if you create a menu item to link to form list view (which display list of forms which you created in the system).

If you set publish up and publish down for a form, it will only be showed during that time (between publish up and publish down). Normally, you just need to leave it empty and the form will be showed until you unpublish it.
