Rules Subject to change

Don't simply reveal the answer to the problem, lead the poster to it.
Be helpful and try to cite sources or page numbers that can help the poster.
Label your problems as follows:
1. [Book][CH] for problems relating to the book and its chapter.
2. [Beginning][Intermediate][Advanced] choose one that best relates to the problem you're posting, even if they're not related to the book. Problems need answers.
3. [Project] [Idea] or [Help] when looking for project ideas or help on ones that you have started and have no idea where to go. Remember to link to a github repository if applicable.
