Two suggestions, number one, make it so your rating must be within 5.0 points of the average rating, so, for example, you can't rate Rabbit Honor Guard 1.0, or rate (no offense to you people) levels that people submitted just for a joke a 10.0. Also, you could be able to get a notification when somebody reviews your level.

And I just thought of the last one, you could be able to browse the "Did you Know?" section.
