Can someone direct me to very simple basic instructions for how to establish collection groupings on the Kindle 3 using Calibre? The stuff I found on the subject was about getting "series" books to display in order within collections and it was confusing to me. I just want to set up basic genre categories from the start but I wouldn't mind doing it in batches for the text and epubs I intend to convert to mobi with Calibre. I have not been successful at registering at the Kindle Collection Manager site and though I very much like the idea of making categories easily from folders I may not be able to figure out that application anyway if it is script based. Thank you
