Spammers are people who barely ever stay on topic. And that's about it. They are ALWAYS in general chat.
Regulars would be people who, like spammers, are usually found in GC but they don't spam. They're just ordinary people.
All Arounders/ Omni Field would be a person who posts in most of the forums and can possibly posted atleast once in all of them. But that's not what makes you an all arounder.
Gaming Nerd are people who are usually found in the gaming forums. This does not, I REAPEAT DOES NOT, mean they are nerds. It's just a title. It's a symbol that you are not a spammer and are usually there to help others when they're in need.
Other. This group is stupid. All you do is specify what group you're in.
