Add functionality to simple SMS notification when users sign up on website. Signup page and php/mysql are completed. Basic integration is already complete, and we need to expand the functionality to include notification to multiple users when appropriate. Notifications are based on client preferences. Specifically, client can choose which days, which hours, and to whom the notifications are sent. Minor additions to mysgl db may be necessary, and code will need to be added to the client's control panel to support the new features.
