Hi glowhen,
Yes, this is possible! Fortuitously it works exactly the way you describe too. 😄

You can set up shared lists through the web/desktop app with these steps.

Keep in mind that you can give tasks within a shared list too, so you can have fairly well partitioned shared responsibility if that's what you're looking for! 😅

Keep me posted on what you find!

Hello. Thank you very much for your help. I can't find a way to add more than one person to a task. Is this possible?

Hi glowhen,
It's not possible to give a task to multiple people, just to add to a shared list and/or to give a task to one person.

I hope this helps but let me know how things go!

Thanks very much for your help.
