Cloudy would not exist today had it not been for the continuous support by the NSF since 1980, most recently through AST 03-07720. NASA has provided support through its LTSA and ATP programs. A generous allotment of time on the high-performance machines of the University of Kentucky Center for Computational Sciences are also gratefully acknowledged.

The grain physics in this version of the code was developed by Peter van Hoof. Robin Williams has led the development of the dynamics and hydrogen molecular network. Ryan Porter is doing the helium-like iso-electronic sequence. The hydrogen molecule is being developed with Gargi Shaw, Phllip Stancil, and Mihaela Mihalache-Leca. Kevin Volk added several new stellar atmosphere options.

C94.01: Peter van Hoof has played a major role in developing new methods and uncovering bugs. Many people helped by finding problems, making suggestions, or simply asking questions about confusing points. These included David Ardila, Marcos Copetti, Kirk Korista, Jifeng Liu, Valentina Luridiana, Pat Romano, Mario Perinotto, Jon Slavin, Kevin Volk.
Beta2: Many thanks for Marcos Diaz, Oli Dors, Dalton de Faria Lopes, Peter van Hoof, Raquel Morales, Henrik Spoon, Lowell Tacconi-Garman, Peter R., Young.
Beta1: Many thanks to Roderick Johnstone, Kirk Korista, and Kevin Volk.

Version 90 of Cloudy was a team effort, involving Kirk Korista, Dima Verner, Jason Ferguson, Jim Kingdon, and Katya Verner. The bugs are mine, but this version would not have been possible without their help.
