The ability to send new roles to Broadbean is activated at an organisational level. But as an Admin, you can decide whether or not to send a role to the Broadbean jobs board posting.
When you reach the final stages of building a role, you will come to the 'Job Distribution' page. The screenshot below details where the 'Post to Boards' button is located, alongside the Broadbean option. If you don't wish to post a role to broadbean, simply omit this action.
If you have any questions on building new roles or using Broadbean, please contact us on the Support team at firstname.lastname@example.org
