Here is the hierarchy
Team Anandtech: 1st and most important
Miniteam: TACube, the Federation, Team within Team Anandtech, and others. These were initially formed as an additional form of friendly competition. Some are now large, some are small. You can join one of these if you would like. I am on TA Cube(the Borg, the Collective, and many other names that we have been called). These are more important to some people than others, but never as important as Team Anandtech.
Individual: That would be you, whether you join a miniteam or not. You are also important, without you, and me, and others, Team Anandtech suffers.
The Herd: This refers to the computers you have cracking for you. Some one or two computers, some very large, in the hundreds. My herd is linked in my sig, as many others are also.
I hope that clears it up for you.
