NupeCode

NupeCode is free/open source software (released under the GNU General Public License) designed for large peer review projects. The code was available via Nupedia's CVS repository. One of the problems experienced by Nupedia during much of its existence was that the software lacked functionality. Much of the missing functionality had been mocked-up using underlined blocks of text that appeared to be hyperlinks, but actually were not.

As part of the project, a new version of the original software (called "NuNupedia") was under development. NuNupedia was implemented for testing at SourceForge, but never reached sufficient development to replace the original software.
