Add "Email" field to member signup, send payment reminders #47
Description
Currently the admin system does not record emails, not sure if this is by design. I think email is a necessary field, especially when the system needs to communicate with the users of the system.
Once emails are a field for the database to store, the system can either connect to an external mailing service (Mailchimp), or send emails from an SMTP server on the same machine to members who owe money on a monthly basis including any new fees.
