There's a lively community around GNOME and we're happy to help you if possible. The following list points to several options you can choose.
However, GNOME interacts with a large number of other software projects. In most cases, the Internet homepage of your distribution is thus a better place to start. So we recommend that you first check the support options of your distribution.
When taking part in the GNOME community, please do try to follow our Code Of Conduct.
Documentation
GNOME comes with full documentation. We provide a User Guide, a System Administrator Guide, and an Accessibility Guide. See our complete documentation.
User forums
To contact others users, get help, and discuss topics around GNOME, join our user forum. Note that developers rarely read its topics, so it's not a proper way to request a feature, or report a bug.
Mailing lists
The GNOME List is a good place to ask general questions about GNOME. Often, your question has been asked before. You can find an answer by browsing or searching the list archive.
IRC channels
The Internet Relay Chat (IRC) network with the largest GNOME presence is GIMPnet (irc.gnome.org port 6667), with the channels #gnome being the main resources.
Report a bug
Something seems to be not working as it should? You desperately miss a certain feature? Be sure to report in GNOME Bugzilla.
