Hi Cylis, you can set a "Job Count" when creating a job pack if you wanted to limit the number of job listings in this way (as shown here on the
JobRoller admin demo), however there is nothing which specifically prevents them from simply buying another job pack in order to post more. Additional settings for that, and for video in a job listing would require customization of the default theme as these are not existing features which can be configured from the JobRoller admin. Thanks.
