Examples:
- Deleting their OWN thread entirely. Instead of having to "edit" everything away, and leaving a mess behind.
- Deleting comments on their OWN topics from other users. Nobody likes inappropriate stuff on their own thread topics, and shouldn't have to always keep relying on waiting for an admin to delete it.
- Deleting their OWN posts/replies to other topics. There are times people may say something, and find out what they said was incorrect. Of course, we can just EDIT everything out already, but then it looks dumb afterwards.
