Usage of FishSpeak for the mouse-loving user

Using the command line seems totally out of this world for most people. A much simpler way to configure FishSpeak is to use a configuration file. The easiest way to create a configuration file is to use the FishSpeak Configuration Cloud Service 2.0! After downloading the configuration file right-click it, select "Open with..." and select FishSpeak.
Depending on your platform that is:

• Windows: FishSpeak.exe
• Mac OS X: FishSpeak - the Application
• FreeBSD/Linux: FishSpeak

For more information about configuring FishSpeak read the manpage
