We do not need to receive emails and event owners do not need to receive emails letting them know who joined an EVENT if they havent paid. As default everyone gets to join events even if they are PAID events. The only way to remove people is to set a rule and have them removed AFTER 1 hour.

I do not like this but ive accepted it.

Can you tell me however how to stop the emails that announce people joined because its of no interest if they choose to not pay and its waisted information.

Same question here.
I've set up RSEvents with RSForm Pro. When one enrolls for an event, the users is shown a RSForm Pro form, instead of the standard RSEvents form. Still, the owner of the event receives a standard RSEvent mail, next to the RSForm pro e-mail that is sent as well. So two mails are sent.
I can't find the setting where to disable the RSEvent e-mail.

Is there a way to configure the product to not allow a registration to complete without payment? I just assumed that this would be an option but I have not found it in the documentation yet. I don't want registrations to be recorded period unless they are completed and I don't consider non-payment as completed. I don't like having to go through all the data I don't need and removing it for proper reporting. My assumption is that this would solve the email problem as well.
