With this app your users can give handshakes to other users. The other user will not get modified until he also gives a handshake. When both users have a handshake they will get a notification. There is also a setting to allow this feature only for specific usergroups. With this setting it is possible to monetize your site.
This app is perfect for dating sites and all others that want to bring people together.
