You can update items to and from GatherContent using either the WordPress bulk edit tool or from the post editor. This allows you to make changes from within WordPress and ensures that those changes are able to be synchronised to GatherContent.
Keep in mind
This is a "destructive operation", meaning any changes in the receiving side will be overwritten, so be sure someone else is not working on the content when you push or pull!
Update in bulk from the WordPress bulk edit tool
Push or pull items in bulk by clicking the "GatherContent Sync" button from the WordPress bulk edit tool. Pull allows for you to import the latest version from GatherContent and push lets you export the content from WordPress to GatherContent.
Update from the post editor meta-box
Push and pull content updates from the post editor page meta-box. Pull allows for you to import the latest version from GatherContent and push lets you export the content from WordPress to GatherContent.
If you have not associated your WordPress content with a Template Mapping, this meta-box will provide the opportunity to do so. So you can also push content from WordPress, which is not currently in GatherContent.
