A friend (with no previous knowledge of Russian) just joined, went to “Store” had a look at “Recommended Items” and picked “Пещера. Е.И.Замятин, Часть первая” - which obviously was way over his level.
I thought that the system figured out which texts were the most suitable according to the level of the member (and/or the accumulated “known words”) but apparently I was wrong.
Unfortunately, the recommended items area is not as effective as it could be, especially for new members for whom we have no statistics. I recommend your friend start in the Beginner category of the Store. We will be working on improving the Store as one of our next major enhancements.
