I totally agree with some points above. I've seen some forums offering a special rank for free, but we could make it harder to get on Aarin, so that only a small range of people could obtain it.
First of all, the user shall be a Contributor.
Secondly, the feature would cost a lot of points (like 1.000.000).
Thirdly, the member shall be active on Aarin for more than a year.
Fourthly, the member shall have a decent amount of points (between 1.000 or 2.000?).
