It's disappointing to say that infogami is not being developed any longer and has been this way for a while, the site is functional but sadly the source code isn't for modern python libraries.
The source code can be found here [infogami/infogami] which is located on Github.
This project was all started by "Aaron Swartz", and is going to be long remembered from his name and hard work put into the code.
Following statements and links
- Here's the installation guide, [Installing Infogami]
- The source may not be any good but the site will still be available to use.
