Infoboards are units that can be connected to your region wide network or not. They also work stand alone if needed. They can collect notecards for you (end send out emails) or give information to the visitors. When connected, information about clicks are sended to the server.
There are different units in this categorie. They won’t work with tiny servers (as those are just for tip jars and displaying donation events on statboards) but with all other actual servers.
