In short: Members can join groups to show opinions and status, as well as forming the base for gaming teams
I really think a Forum Groups should be added as a subsection.
Groups would work like this:
Anybody can create a group for people of their same opinion, or just friends and teams e.g: "I <3 Pancakes" "Aliens are awsome" "DELTA combat team"...
They should be either freely open (everybody can join them),or open (you can apply), or closed (you have to be put in it by the leader).
groups would have to be approved by a modorator to avoid immature or §2b groups
The reason why clans would not work out for this is that clans are closed and´made for gaming together (groups will be pure social), as well as almost all clan leaders not allowing multiclanning
Name tags would not be necesarry but it would probably be <name> as it is the only bracket left and <@> is sort of what groups should be and is a group
I think this would be a great addition to the Forums, as it is easily done, and would greatly improve the social factor because people can show, and spread opinions by joining a group
