There's a livid community around GNOME and we're happy to help you if possible. The following list points to several options you can choose.
When taking part in the GNOME community, please do try to follow our Code Of Conduct.
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. We recommend that you first check the support options of your distribution.
GNOME comes with full documentation. We provide a User Guide, a System Administrator Guide, and an Accessability Guide, see our complete documentation.
To contact others users, get help, and discuss topics around GNOME, join our user forum. Note that developers seldomly read its topics, so it's not a proper way request a feature, or report a bug.
Something seems to be not working as it should? You desperatly miss a certain feature? Be sure to report in GNOME Bugzilla. If you're new to Bugzilla, you may find the Simple Bug Assistant easier to use.

The GNOME List is a good place to ask general questions about GNOME. Often, your question was already asked by someone else. You can find an answer by browsing or searching the list archive.
The Internet Relay Chat (IRC) network with the largest GNOME presence is GIMPnet, with the channels #gnome-help (for getting help with GNOME) and #gnome (for developer discussion) being the main resources.
