In the #blogs.de IRC channel I was asked by Marcus (the author of Moinx) to test if Moinx would run on Mac OSX Tiger. So I checked it. Marcus could not know that I was searching for something like this: A easy to install and manage Wiki.
Just download and drag the Moinx Icon to the application folder and you got a locally available Wiki. You can even configure it to be accessible via the network… great thing.
