I'm setting up a membership site and I'm not sure how to handle renewals. I want members to be charged automatically instead of manually renewing each time. I don't know what tools or settings I need to make this work. Do I need a specific payment gateway? Will members get reminders before they are charged? I also want to avoid any payment issues that could cause cancellations. How do you set up automatic renewals for a membership site?
