Tools
Currently, there are two tools: Search, and Flashcards.
As the name implies, the search tool will help you to search through current and past materials. This will be most helpful for coaches, but quizzers should also find it useful. This will likely be the best place to start for most people.
Flashcards will be the most helpful tool for quizzers. It is also self-explanatory, but in short it provides the user with a list of flashcards generated from the user's settings. The principle is very simple: the tool shows you one side of the card and your goal is to recall of the others side. You can further customize your experience by changing the mode, which will affect how you are supposed to answer the flashcards.
