 A "list" event is defined as having a list of public and/or private tags. Public tags will be listed in the event `tags`. Private tags will be encrypted in the event `content`. Encryption for private tags will use [NIP-04 - Encrypted Direct Message](04.md) encryption, using the list author's private and public key for the shared secret. A distinct event kind should be used for each list type created.
 
-If a list type should only be defined once per user (like the 'Mute' list), the list type's events should follow the specification for [NIP-16 - Replaceable Events](16.md). These lists may be referred to as 'replaceable lists'.

-Otherwise, the list type's events should follow the specification for [NIP-33 - Parameterized Replaceable Events](33.md), where the list name will be used as the 'd' parameter. These lists may be referred to as 'parameterized replaceable lists'.
+If a list should only be defined once per user (like the "mute" list) the list is declared as a _replaceable event_. These lists may be referred to as "replaceable lists". Otherwise, the list is a _parameterized replaceable event_ and the list name will be used as the `d` tag. These lists may be referred to as "parameterized replaceable lists".
