I have an idea kidzsearch!
When a user gets 250,000 points, they should be able to get a feature. It's like an advice column but it's a top-level category that they can name whatever they want. Features would be very exclusive and the user gets their feature to post in. If the user gets inactive, their feature is deleted or converted into an advice column!
It's like this
Almost anyone can make a club if the topic is interesting
1,000 points get's you a blog
25,000 points get's you an advice column
250,000 points get's you a feature
1,000,000 points gives you a special feature.
The reason why there should be features is what is the point of earning more than 25,000 points if it doesn't get you any more privileges? This would motivate people to become more active and get more than 25,000 points.
