Yeah, the limit could be 2 friends, so the total graders would be max 2 friends and 3 whos not a friend. The way it could work would be like when you choose to grade homework, it choose randomly from the topics u have started, så the first to start would be the first who clicks and get it. I don't see a problem there

I just had the same thought but a bit different.

I was thinking of foldable chapters, so you can click on what you actually need to reed. I'm librarian on the danish site and at this time I'm making a really long book.

I don't think everything needs its own chapter, especially not it it's on the lexicon too, but som longer chapters could need it.
