This would be helpful in all scenario that
- require different groups of people work (in sequences) on the same board and
- shall prevent early groups to a.) alter their original results later and/or b.) see, what later groups add to / do on the board
Right now, I have only the original link created to share access to the board to anonymous users. There is no way to differentiate rights between different populations accessing the same link. Creating teams / adding team members might solve this, but that would eliminate anonymity and would require paid members.
Allowing to reset the link (like e.g. Mural does) would solve this problem: I could simply use the new link to grant access to the board. Saving the original would allow for a copy to the original participants.
