How do u get into a user group?

Im new to the "Forum" and id like to know how I get into a user group. Can someone tell me how?

The usergroups here are (name color coded):

Red - A red username applies only to the Administrators of the forum, who work directly for Haypi, Inc. Ltd.

Light Blue/Teal - These users are Forum Moderators. These are composed of excellent Experts from the game servers, and you yourself can nominate forum users to be Forum Moderators here.

Orange - These users are Experts on an in-game server. You can nominate players to be Experts here on the appropiate Server's thread.

Yellow (in CA Black style [Default])/Dark Blue (prosilver style) - Forum users with names in this color are regular players who have logged into the forums at least once. This is the color that you will find your own name when starting out on the forums, unless of course you first log in as an Expert.

White - Users with white usernames have been banned.

I have only seen this once but thought I'd add it in anyways:
Extreme Bright Yellow (Not to be confused with a normal user) - User deleted by a Mod who has been IP Banned. Profile unavailable because he's essentially nonexistent, although you can still see his posts.

EDIT: Nevermind, misread. >_<

User deleted by a Mod who has been IP Banned. Profile unavailable because he's essentially nonexistent, although you can still see his posts.

Close enough.. xD
When I read the topic where what's-his-name that we're talking was banned it said his IP and emails were all blocked, and his accounts were all deleted. Justice is served o.o
