They make use of a so-called Java applet to make chatrooms on the Web possible. This means that you need a browser that supports the Java technology. If you work with Windows 95 and a browser version 3.0 or higher, you should not have problems entering the chatroom.
Some people try to enter the chatroom from the network of the company they work for.
In this case, the presence of a firewall can make it impossible to enter the chatroom. Please click the gray button to enter. You can't use nicknames that are used by members. This might be a reason why you can't enter the ZaZ chatroom.
