The Anonymous Publishing LR module is part of the Anonymous Publishing project.
When this submodule is enabled, when a user that already has published content using Anonymous publishing CL registers registers on the site with the same email address as he or she used when creating anonymous postings, he or her will see a tab named “Claim anonymous posts” on the “my account” profile page (see screenshot below). This tab will allow the user to “claim” the posts they created as an anonymous publisher for his/her profile (i.e. if “claimed”, these posts will be owned by their logged in profile).
There is no administrative interface to the Anonymous publishing LR submodule. To make the tab appear on the user's profile page. enable the submodule. To make the tab disappear, disable the submodule.
Note that since this feature uses the email addresses to link the old content to the new user, it is incompatible with the privacy functions to purge email addresses available in the panel under the “Privacy” tab.
