The ladies who manage and create our schedules use a laptop to create the schedules and then load them on Sunday mornings. Our question is; how do we load the songs into the song database?

Put the new songs in a schedule and save it to a flash drive (or other portable drive). Be sure to use that the Pack files in schedule option is checked in the dialog box that pops up to select the drive/folder to save it to so any backgrounds or other media files in them save with it. Now open that schedule file on the second computer and use the Check Schedule for Changes option to save them into the second computer's database.See the link below for more information on that.
