Currently there is no importer built into the theme for this purpose as there is with some of our other themes. Using the built-in Wordpress import/export tool you can already import jobs as XML files, but it can be difficult to bulk import jobs added manually to a XML file as the structure is too complex. There is a
plugin that allows importing posts (or other custom post types) as *.csv files, but it also needs some understanding about the right columns structure and the taxonomies and posts types used by JobRoller. Ultimately you would need knowledge of mysql admin if you were looking to do this. Thanks.
