PyCharm has many places that you can get support from. The bundled documentation can often be the only thing that you need.

If you're stuck on a problem with regards to PyCharm, Stack Overflow is probably the best site for such a thing. I myself have received a lot of support on this site, and you can ask a question with the PyCharm tag.

There is also a PyCharm forum, forum.jetbrains.com/forum/PyCharm, which you can use if Stack Overflow fails to answer your question. I recommend Stack Overflow only because it is a far more active site, and the answers often come within 15 minutes of the question being asked.

Another site that I must recommend is the JetBrains PyCharm blog—blog.jetbrains.com/pycharm. It gives you all the latest news on all things PyCharm, and furthermore, gives you tutorials on how to use new features. This is especially important since they announce RC candidates in those EAP programs, which are far more stable than the other EAP releases.
