hello as well, and looking forward to your sections Todd already gave you all the necessary details on how to read the stage directions, but I also would like to add that before you start recording, we strongly advice to complete a one-minute-test first. This is to check that your technical settings are all up to LV standard.
You can read all about it here: https://wiki.librivox.org/index.php?title=1-Minute_Test
Please post the test in the Listeners Wanted forum: viewforum.php?f=21 and someone will check it and give you feedback or advice if needed.
As soon as the test is ok'ed, please post the results back here, and we can assign you the sections officially. For that we would need to open a personal reader page for you, so please also tell us which reader name you want to go by. Can be the same as the forum name or your real name, or whatever.
Good luck with the test !
