Once upon a time in the mythical ages of old there was a Team board, but TGC ended up removing it. It was kinda abused and when you consider their target audiences for their products, I think you're gonna attract novices trying to fetch people up without a first idea of what to do or really be serious in it. I don't know if they'd consider opening another one, but I don't believe there's been much of a demand for one.
However, I believe legit team requests have been allowed to go through before if they've had substance. Team requests appear once in a blue moon, so I wouldn't quote me on that as I have the memory of a jellyfish. But if you give more detail of what you're looking for, maybe we can help point you in the right direction?
