How it works[edit]

StayFriends enables its members to find back their friends from school. Schools can be searched by State (Land) and city. A user can add all the schools he attended on his profile by giving the start and end year of each of them.

Users can perform searches on the database by last name, first name, city, and school. Searches of last names can be done using the last name used at school and the current lastname.

While some functions are free, such as searching for old friends, organizing class reunions, or viewing of class photos, others require gold membership. These premium features include the possibility to read messages received and display all the photos and profile information. Communication without restriction is possible only if the sender or the receiver is a gold member - users can contact each other only if one of them paid for the service.


StayFriends requires users to register with their real first and last names. An online mailbox service makes it possible to send and receive messages on the website without disclosing one's e-mail address. A newsletter is sent every two months by e-mail.
