Following the implementation of the FogBugz performance UI and the delivery of the free FogCreek timesheet plugin we are shuttering development of Clark Kent.
If you run FogBugz on your own server you can still download Clark Kent 1.1.3 from Fog Creek or use the Fog Creek timesheet plugin.
Alternatively if you run FogBugz on your own server and you’d like to customize Clark Kent beyond 1.1.3 you can get the source code from GitHub here.
You will need to setup a Visual Studio project and compile the project accordingly before being able to deploy it to your own server.
