Easy Content Deployment for WordPress: RAMP

RAMP allows you to make all the changes you need in your staging environment, then selectively push these changes to your production site. You can set up a new section of your site, upload some images to fill out a nice carousel for it, and add a link to it on your home page. Once this content has been reviewed and approved, you can go to your RAMP page, select these content changes, and push them to your production site.
