This add-on is no longer in beta and can be considered feature complete and stable.
Changes from beta:
- Only send warning email if the user has an email address
 
- Fix category sorting
 
- Add {userId} as replacable for warning conversation
 
- On issuing a warning, redirect back to the content via the getContentUrl() instead of referrer
 
- Display user's warning count on the "previous warning" bar, make the previous warning count configurable (default 5) and link to the rest of the warnings if not all are displayed.
