It is possible to change registrant behaviour such as setting all registrants to be auto-aproved or to require a spending limit before registering by changing the Auctioneer settings. Click here to see how to access your Auctioneer settings.
Once you are editing the auctioneer, go to the Main Settings tab and scroll to the bottom of the page. Here you will see the option to switch on or off the ability to auto-approve all registrants. You can also select to require a spending limit from your registrants. Finally, you can change the default location that users create their accounts from (although users can change this themselves during sign up). The available options are boxed in red below:
Please note that some options are crossed and labelled as deprecated above - these are either unavailable to you or deprecated functionality. Please do not make changes to these settings.
Once you have made any required changes, click Save Auctioneer at the top of the screen. Please note that this will immediately apply to your auctions so only make these changes when you are ready for them to go live.
