Is it possible for you to submit your 1-minute test in the Listeners Forum first? This is just to make sure your settings are fine.
Once you get a green light for your test, you're good to go!
Also, what would your preferred "Display Name" be on your own LibriVox page? This can be different from your username here in the forum.
Feel free to tell us your personal website so that we can put a link there, too!
I'll reserve section 06 (CHAPTER III Part 3) for you for the time being.
