Prefilled from your account — change either if this meeting goes out under a different name.
The participants
Your own team and anyone outside it. Email is optional — but only people with one
get the confirmation when you lock a time in.
Commas, semicolons, spaces or new lines all work. Name <email> is
understood, and anyone already in your directory keeps their proper name.
Creating the board sends nothing. Participants are only emailed when you invite them.
