Aten is maintained entirely by T. Youngs. However, many people have contributed useful thoughts, ideas, bugfixes, and motivation to the project over its lifetime. These people are, in no particular order:

A. K. Croft and crew (Mac afficionado, supreme fault-finders)

S. Cromie (algebraic guidance)

A. Elena (bug-finder extraordinaire, ‘pathological case’-locator, Windows / Mac building and packaging)

D. Pashov (Windows / Mac building and packaging)

S. Norman (icon judgment)

N. C. Forero-Martinez and M. Smyth (bug finding, bug finding, and bug finding)
