Is there any benefit to allowing anonymous edits?
e.g. on some topics, some users might prefer to share their knowledge anonymously so that readers don't get the incorrect impression that they hold certain views.
That's an interesting point. The difficulty arises regarding legal attribution under the CC License. Since the adoption of WE we have always required users to register an account. It would be possible for a user to create another account so as to disassociate edits from a public persona. Under law, WikiEducator might be required to disclose certain information and this is the kind of detail which should be clearly disclosed in the privacy policy so that all users are clear regarding what personal information is held, and how it will be used.
