If you select "I want to make a recurring donation", you will be registering to make a credit card donation every month, 3 months, or year. After you complete this initial donation, future donations will be made automatically. For example, if you choose to make a recurring monthly donation of $10.00, your next donation of $10.00 will be automatically charged to your account one month from today.
You will receive an email receipt for each recurring donation with a link to the site where you can login and change your donation options (amount, frequency, billing information, etc.) at any time. Of course, you will also be able to cancel your recurring donation at any point in the future.
