Hi Tim, in answer to your questions:
1) Aside from the option to charge for listings, you can set it up so that employers can subscribe in order to be able to view resumes. This can be seen on the "Browse Resumes Pricing" tab of the
JobRoller admin demo.
2) There is no option to import jobs from other sources outside of the built in integration for Indeed job feeds, or the SimplyHired feed Plugin sold separately in the
AppThemes marketplace. It would require customization of the default theme on your part if you were looking to scrape job listings from other sites as you describe. Thanks.
