My idea is for the forums. I think a new feature should be added to the list of things you can do when you first create a thread. The ability for the creator of the thread to approve of the comments before it is visible to everyone. Basically the owner of the thread has to approve of the comment before it can be viewed by the public. This can help against flame threads and other things, such as derailing topics. This ability should be able to be turned on whenever the owner chooses, whether it be in the thread creation or after the thread has been published. Of course staff will be able to bypass the acceptance of the thread owner.
