Athlete Forward is very intuitive by design. Or at least we have tried to make it so. All it takes is a few minutes of play time to discover the cool things it does, and we encourage you to spend a few minutes clicking, hovering and dragging around. You won’t break anything (and if you do, then it’s a bug and we would appreciate if you can report it at firstname.lastname@example.org).
We suggest you start by getting familiarized with the User Profile and the Dashboard. The Library and the Groups sections will not be available for our initial release as we are putting the final touches into their functionality.
