The most convenient way to give is probably online. Keep in mind that a small processing fee is assessed to all online payments. If you would like to avoid this then consider sending a check. You can give online by clicking the link below. Online donations are handled by a third-party, SimpleGive. You will have the option to give either a one-time gift, or to set up recurring giving using a credit card or electronic funds transfer (EFT). You will also be able to designate the specific person, project, or team to whom you wish to give.
