Internet Relay Chat (IRC)
For more immediate discussion, you may join the #freedoom channel on the OFTC network. Discussion in IRC is less formal than the forums, and more coverage can generally be had via the forums, so anything on the order of new directions Freedoom should take and such belongs on the forums.
Freedoom has been contributed to by over 90 people, however only a handful of people manage the maintenance of the project. Contact Mike if you have any queries not answered on this site or forum. However, any bug reports and such belong on the bug tracker and not in a personal e-mail!
