Would aMember work for accepting online registrations for in-person courses? Some specific requirements are below. 1. Can I import courses and the import format supported. 2. For the short term, there is a need to process payments manually. The user would register, then call with their CC info. Is there a way to go into the admin and mark the course registration somehow as paid? 3. Would like to allow users to transfer from the date and / or time of the course they registered for to another day / time. 4. Is a standby list possible?
