358120 Email Reminder

I need a simple reminder form that will send recurring reminders to registered users. This tool will consist of only two pages. Customer's Profile and Customer's Reminders Customer's Profile: Upon registering, profile will include customer's name, address, and email address, along with a button to add reminders which will take the customer to his/her reminders page. Customer's Reminders: This page will include a form to create new reminders and display any pending or existing reminders. Form will consist of product name, date of product installation, and reminder interval (how often must the reminder be sent to customer's email address. Automatic cron job is required. Thanks Sid
