Would it be possible to add an option to force users to register and disable the ad access code functionality?
I think this feature is unneccessary complication in the case of my site as I’d rather just have them register.
Admin Answers:
The plugin is not integrated with wordpress in a way that would make it possible for your users to manage their ads without the access code. It would be possible I suppose to do an integration so that the plugin uses the wp registration information but I can’t estimate when I will have the opportunity to add this ability.
