The developers, designers and testers who gave you Firebird and several of the drivers are members of the Firebird open source project at SourceForge, that amazing virtual community that is home to thousands of open source software teams. The Firebird project's address there is http://sourceforge.net/projects/firebird/. At that site are the source code tree, the download packages and a number of technical files related to the development and testing of the code bases.
The Firebird Project developers and testers use an email list forum – firstname.lastname@example.org – as their "virtual laboratory" for communicating with one another about their work on enhancements, bug-fixing and producing new versions of Firebird.
Anyone who is interested in watching their progress can join this forum. However, user support questions are a distraction which they do not welcome. Please do not try to post your user support questions there! These belong in the firebird-support group.
