We don't have any permanent procedure to select regular chat members as VIPs.

Chat Administrators & Chat moderators regularly keep an eye on members who are spending more time on chat regularly, how active they are in main/ lobby, positive behavior etc. and then we select some of them as VIPs.

99% of time, only people who have been member in more than 3 months will be selected for this post.

Also only members who come to chat regularly with same username will be eligible for nomination, instead of changing usernames everyday.
