The most popular online discussion forum for getting help with Blender is the Questions & Answers forum at blenderartists.org. Feel free to draw on the wealth of knowledge of experienced Blender gurus, or take a minute to help out a fellow user.
The blender.org forums are for tech support and development tips along with questions and answers about Blender's source code and the Blender Foundation. It is directed towards user support, rather it focuses on the internals of Blender and the organization that supports it, to those who want to be involved with blender.org projects.
In addition to the official Blender forums, there are many independent community websites in which you can ask questions or share art.
