+A special event with kind `3`, meaning "contact list" is defined as having a list of `p`, `t`, `e` or `a` tags, one for each of the profiles, hashtags and other events such as communities or chats one is following.
 
-Each tag entry should contain the key for the profile, a relay URL where events from that key can be found (can be set to an empty string if not needed), and a local name (or "petname") for that profile (can also be set to an empty string or not provided), i.e., `["p", <32-bytes hex key>, <main relay URL>, <petname>]`. The `content` can be anything and should be ignored.
