TutorBase is a PHP application to manage class tutors. Tutors are stored in a MySQL database. Tutors can sign up, and are required to validate their emails before being listed. Listed tutors can log in and change any aspect of their profile or unlist themselves. Administrators can send emails to all tutors, change class listings, and change the profile of or delete any tutor.
PHPMyIbill allows a membership-based site to manage its users and let them sign up automatically by credit card using the Ibill system. The webmaster can, via the administration page, see in real time how many members sign up daily, edit or delete users, email all of them at once, set users active or inactive, etc. On the user side, customers sign in only once per session to access all your protected pages. If they forget their password, they can have it emailed to them automatically without your intervention.
