# 18: Acknowledgments

Developing Gri was made easier by suggestions and bug reports from many users, among whom are: Ivo Alxneit, Karin Bryan, Sara Bennett, Luke Blaikie, Dave Brickman, Clyde Clements, Pierre Flament, Peter Galbraith, Dave Hebert, Alejandro López-Valencia, Steve Matheson, Ed Nather, Carl Osterwisch, Richard Andrew Miles Outerbridge, Brian May, Jinyu Sheng, Toru Suzuki, Keith Thompson, David Trueman, and George White.

Some of these folks also suggested detailed improvements to the C++ code of Gri, not an easy task given the complexity and length of the code.

All of these, and many users with whom I've interacted over the years, I thank warmly.
