Jennifer Beaudin has done a terrific job recently creating a very useful documentation section on the MyExperience Wiki called How Do I...? This is sort of like a hybrid FAQ/Getting Started guide that covers some of the most important points about MyExperience and will surely save you time if you give it a read. I strongly recommend taking a look here.
Note that the Wiki is constantly improving. As we find the time, we continue to add more helpful content and fill out incomplete sections.
