Allow anonymous posting on the forum. It’s a setting you can toggle. Users will be called something like @anon1 where 1 is a very large number. (e.g. anon675121434654)
minimum trust level: 2
anonymous account duration minutes site setting sets the period of time that an anonymous account will remain in place after a user has entered and then exited anonymous mode. This setting defaults to 10080 minutes (7 days.) With the default value for this setting, if a user exits anonymous mode and then re-enters it within 7 days, they will be logged back into their previous anonymous account. If the user waits longer than 7 days before re-entering anonymous mode, a new anonymous account will be created for them.
When anonymous mode is enabled, logged in users are able to switch from their normal account to an anonymous account. This allows users to create topics and replies without any details being displayed in the Discourse user interface to connect the anonymous user with its associated account.
