Quantum GIS is a community driven GIS project. The web site, the source code (SVN), the bug tracker and the mailing lists are hosted and partly maintained at the Open Source Geospatial Foundation (OSGeo). The work of the QGIS project management process is spread between an international team of developers and GIS users who each have a specific area of resposibility. For detailed information have a look at our contact web site and the Project Organigram.
Our dedicated documentation team has put together user manuals in multiple languages.
Getting Support for QGIS
The QGIS project has a number of support channels. Like many open source projects, these are loosely coupled.
GIS StackExchange allows you to ask questions and get answers from a wide range of users and experts in the GIS realm. If you have a question specific to QGIS, tag it with the qgis keyword, otherwise use an appropriate tag.Since StackExchange is question-based, you should not ask multiple questions in a single posting. Also, make sure you flag the question as answered once you receive a satisfactory response.
The QGIS project maintains a number of mailing lists. For most people, the two of interest are qgis-user and qgis-developer:
If you just want to browse or search the mailing lists without subscribing, they are available on Nabble.
IRC (Internet Relay Chat) is a method of communication used widely by open source communities. On any given day you will find both developers, contributors, and users monitoring the #qgis channel on irc.freenode.net.
To use IRC, you’ll need a client application for your computer, tablet, or smartphone.
Here are a couple of guidelines for using the #qgis channel:
The QGIS IRC community is very friendly and helpful. Give it a try!
