This article is from the GNU Chess and XBoard FAQ, by Tim Mann firstname.lastname@example.org with numerous contributions by others.
Stuart Cracraft is the GNU Chess project coordinator. Currently no one
seems to be working on the GNU Chess engine itself. Conor McCarthy is
responsible for GNU Chess 4.xx for Windows. Tim Mann maintains this FAQ
and is the lead developer on XBoard and WinBoard, but he has little time
to spend on the project. Evan Welsh, the author of cmail, is not
actively working on it but does fix bugs when they are reported.
