Each and every card on Supernotes has the ability to be shared using a share link. By default cards are not shared and are only viewable to you.
You can generate a new share link in the 'Sharing Options' of a card (third icon along the bottom). This code allows other users on Supernotes to join and interact with a card, with varying permissions.
Share links are based on our a code is comprised of four randomised English words like so,

If you are the Author or a Moderator of a Card, you have the power to 'Freeze' all the share links of a card in one go. This will prevent any new user from joining via any of the links, and current members will be unaffected by this change.
To unfreeze the share links, just click the button again.
