I am looking for a membership management plugin to allow a nonprofit organization to accept membership payments from their WordPress website. This is not a WordPress paid membership site, restricting access to the website itself, but a plugin to pay for membership to the organization. Client has multiple membership levels and should allow for several extra fields to be collected (such as Business Name, FAX, etc.), and the plugin should have a feature that sends out reminder emails just before membership period expires.
Anyone know of such an animal?
