First of all, I appreciate the hard work of the creator for building the site and migrating so many courses from Memrise. Thanks a lot. With that said, I am a bit unsure of how to go about Reviewing. It looks like, if I want to review, I would need to review all the items that I have added to my learning queue? Do the reviews get scheduled based on some intervals or is it that we need to review all items that have been added to learning queue, each time we want to do a review session? If I am missing something, please let me know. I see two buttons: "Level up" and "Review all", but not sure what "Level up" means in this context. Also, in the village section, there are numbers showing besides three different icons. But what do those icons/numbers mean? And is there something we need to do inside village? As I can't seem to click on anything when in Village page.
