Invite collaborators
Open the menu on the list you want to share and pick Share. Enter a label/email to generate an invite link.
Copy the invite link from the dialog and share it yourself (chat, email, text). The app does not send emails.
Only collaborators on a list can add, update, move, or complete items.
You can remove access at any time from the Share dialog (you cannot remove the last collaborator).
Everyone (including existing users) must accept the invite before the list shows up for them.
Accept an invite
Open the invite link and sign in; the list will be added to your menu automatically.
Already signed in? Visiting a /main?invite=... link accepts it in place.
Use the same email/username the invite was sent to for a smooth accept.
Once accepted, the list behaves like any other - no special steps needed.
