Pulling word-for-word from other sources gets into the rocky area of assigning credit and plagiarism. We can handle this by adding the link to the 'Useful Links and Resources' section. Credit can then be assigned for each question or section by referencing that link (e.g., with @Bell). Go ahead and add the questions/topics and we'll refine as we go. In the event that a consensus can't be reached, I'll make the final call.
