You can submit bugs at bugtracker (no need to register), or join the mailing-list — don’t worry about the “Undertype” name, as Fontmatrix primarily belongs to this bigger project, even if it’s now independent. We also maintain a #fontmatrix channel at Freenode (we’ve embedded a webchat client under Fast IRC that you can use if you’re really unused to IRC thing).
The Gna! bug tracker and the Freenode channel no longer exist. The mailing list is archived. Today, bugs and questions go to the issue tracker on GitHub.
From the old Fontmatrix website: the text as it was written, with links to archived copies where the originals are gone. Archived original. All old pages.
