Peer review can not be done by a beginner. It takes quite some experience to know what is on-topic and off-topic, what is a copyright violation or not.
So, I suggest hiding the navigation drawer's "Review" item from users who have not yet reached level 10.
I chose 10 because it is a round number, but I am open to other suggestions.
This means storing the level somewhere when it is retrieved from the server (in the Achievements activity). People who have never opened the Achievements activity will not see the "Review" item, because their level is unknown.
