I've been thinking about the proper place for a reading group and I was thinking that the kind 11 discussions would work well.
You could have a kind 11 containing a
["t", "readings"] tag, and then tags defining the book to be discussed, and we could group and sort by title or author.
Then I could make sure that they also appear grouped on Jumble Discussions, under "Literature" > "Readings".
Like ["subject", "Poetics"]
or ["author", "Aristotle"]
