Thank you, welcome to Librivox, and more specifically to the drama forum. I see you have posted the One Minute Test so we can verify that your equipment is all set up properly. Did you also get the addiction warning?
Most of how things work is the same everywhere at Librivox, but there are a few special things about drams. Here is a short summary for the important special rules in drama:
1) you don't have to read an intro or outro disclaimer, this will be done by the narrator. Instead, record your voice credit at the beginning of the file using the words in the MW, which for your role should be: "The Mailing Clerk, Simpson Peavy, read by XXXX" (whatever you use for your reader name)
2) then browse through the text and record all the lines you have to speak. Also include any "All" lines while your character is on stage. For a big role it may be good to read the entire play to get into character, but at least it would be good to read a bit around your lines, see what the others are saying, so you can better "react" to them. Just be as expressive (according to the character) as you can in your role.
3) if there are pointers in the text qualifying your voice, like [laughs] or [whines], an added bonus would be that you act those out in your reading, if possible, to make it all more interesting.
4) You prepare and upload a separate file for each Act that your character is in. (Note - the section numbers change as I move stuff around on the MW, so remember character name, not section numbers.) Your file will be proof-listened, and you may receive some notes on corrections and their time locations in your file. These will be posted in the forum and show in the Magic Window marked as "See PL Notes" - please cut corrections into your file to update it (don't re-record the entire thing! that makes more work for everyone and risks new errors) and upload a new file (SAME NAME) in a reasonable time - like before your voice and equipment setup change and everything sounds different!
5) and most importantly: please leave enough space between each of your speeches, preferably 4-5 seconds or more. Even when you have the stage directions in the middle of your speech (for example: [kisses her hand]), also leave 4-5 seconds of pause there, because our editor (me) later on has to copy all your parts and paste them into his (my) master file and it's helpful if he (me) has enough space to fiddle with
That's it, I think. Just have fun acting out. And post any questions here.
