For anyone who wants to be in on my choral arrangement, please PM me to let me know you're interested, and either send me a sample of your vocal range or if you know your register (tenor, soprano, etc.) that's also fine. I want to write in the appropriate number of parts and in the correct register when I get started. Then I can send out a synth example of the part I'd like you to sing. Don't worry too much about getting it perfect; non-verbal vocals are super easy to clean up and I can do pitch correction and fix timing issues on my end. I haven't started production yet, so no rush.
I may also reach out to some people on the project if they don't volunteer themselves.
