The Reporter (a regular member) gets an alert that their thread has moved (When moved from Report a Post > Reports Bin).
I believe it shouldn't happen since both forums are hidden.
If the "from forum" is not visible to the thread starter, leave "Notify thread starter of this action." unchecked by default.
While I am suggesting Report a Post fixes:
Moderators should automatically subscribe to Reports that they make themselves.
In other words: If the Reporter can view the Report a Post forum, he or she should be subscribed to the report so he or she can see the responses. Makes moderation easier.
