Resetting is the solution to most weird little problems, it seems.

Okay, I'm waiting to see what Lilly (and Grooks?) have prepared, so that we don't do the same things over and over again.
But the "borrowing library books" entry should be easy, assuming we have already explained about authorizing and ADE:
To borrow library books you need to have ADE installed, to have authorized your reader, and to be a member of a library that supports ebook loaning. You can hopefully find one near you here:
http://search.overdrive.com/
You can browse your library's catalog and choose the books you want to borrow (or place on hold if they are already borrowed by someone else, in which case you will be notified when they are returned), just like in an ebook store. Rules about how many books you may borrow and for how long may vary. Download and open your books with ADE. They will appear under "Borrowed" in library view, with a sign on the cover stating how many days you have left. You can load the books on your reader your usual preferred way. On the reader you will see a little clock next to the title, reminding you again of the days you have left. If you are done early, you can "return" the books early through ADE (click on the small arrow next to the book's cover, and select "return borrowed item"). Don't do this too often though, or you may raise alarms and be blocked from borrowing more for some time period.
You can borrow epub and pdf books from your library, but be careful to never have both epub and pdf library books on your reader at the same time, as there is a conflict and you will not be able to access them.
After the borrowing period is over, you will not have access to your borrowed books any more, and you can delete them.
Feel free to add and edit as you please, and correct any mistakes
