Alright, well all the principal characters are good to go. I took a look at "last active" dates for the people I'm missing, and most of them I think I can safely say won't be too upset with us continuing.
Here's how things should (hopefully) go:
The work for directors and timers will be much more divided up. As of now, I am technically the only timer...
Directors: you now have a handy to-do list like the actors have, informing you of which parts are ready for your attention. Once an actor has posted a part, you are responsible for downloading all pieces, ensuring there is adequate audio quality with no background interruptions, all lines are accounted for, and there is at least one clean take of each line.
Timers: (AniDragon, for now) I would like to try and skype with you sometime to go over the procedure in detail. Once a chapter has all parts approved by various directors, the timer will download all parts and assemble the chapter into a finished product. For now, I would prefer for all final chapters to go through me before they are posted.
