Spacewalk is licensed under the General Public License (GPLv2).
There's a few ways to get in touch with the Spacewalk developers, depending on your needs. We've outlined each communication method below:
Spacewalk has three mailing lists. One is primarily for general announcements, another for the discussion of the usage of Spacewalk, and yet another for discussion amongst contributors to discuss project development. (Subscription is required to post to lists)
As for mailing list policies, we think that the Fedora mailing list guidelines are a reasonable and fair set of standards to ask all community members to adhere to. In a nutshell, be respectful and aware that the list is public and archived. If you don't have much experience communicating on free & open source project lists, you will definitely want to look over the Fedora mailing list guidelines to know what to expect and how to communicate effectively.
We have one main IRC channel for both development and user discussion. This channel is:
Not familiar with IRC? Check out http://irchelp.org/ for some quick start guides and tutorials. You may want to try XChat as your IRC client - it is a popular IRC program available in most Linux distributions including Fedora and Red Hat Enterprise Linux.
NOTE: irc.freenode.net has an IRC 'nick' (nickname, the name you go by in chat) registration system. Some irc.freenode.net channels require that you identify with the server every time you log in. This identification is also required for private messages on the network (no, they're not ignoring you; you probably just haven't identified with the registration system!) For more information, please consult the Freenode Frequently-Asked Questions page on user registration.
As on our mailing list, please be respectful in our IRC channel. If no one seems to be responding to your requests in IRC, feel free to ask your questions on the mailing list. (It's quite common for IRC users to 'idle' their nicks in a channel so they can catch up on any conversation they missed later on.)
Reporting of all bugs and enhancements for Spacewalk will be done within Bugzilla.
