Unlimited Editing is a great reward for logged-in commenters
Unlimited Timer Option
Another popular feature is you can enable unlimited editing for logged-in users.
Unlimited Editing and Anonymous Users: Unlimited editing is not possible for anonymous (non-logged-in users). Since anonymous users do not have an account, comment editing is cookie based, which limits the editing experience to the user's current session.
With Unlimited Editing enabled, users are shown a "Click to Edit" button with no timer present.
Unlimited Editing on the Frontend
Users will be able to edit their comment as long as unlimited editing is enabled.
Enable email notifications and comment logging to keep track of edits.
