No problem at all.
The Discord is just an easy way for me to collet and inform the team.
You will all be given a personal google doc with the script and guiding. there you can make all the notes and comments you wish and I will then collets all the docs and make my editing.
So what I do need is your google account (gmail) and you are in! And if you do not have any google we find another way.
We just need to communicate around Discord (BTW I respect if you do not work with Discord but can recommend getting a user profile)
