The Dinner Co-op was a group of (mostly) graduate students at Carnegie Mellon University in the 1980s and 1990s.
The Dinner Co-op website, http://dinnercoop.cs.cmu.edu/dinnercoop/, was the largest food and cooking website on the internet in 1996, and we received several design and content awards.
In January 2018, CMU retired the website. I still have the tarball if anyone would like to look at it for archaeological purposes.
I have updated the collection of recipes. Here is the 3rd edition of the Dinner Co-op Recipe Collection
