I absolutely agree! The forums are a far more permanent and convenient way to communicate.
Unfortunately, the problem has several angles. First the GG forums where decoupled from the old TGC main forums which separated this community from the rest of the old guard. The original TGC forums are pretty dead as well now. Then there were the Steam Forums where it was clear that a lot of the more casual users were not aware that this forum here exists.
Then we introduced 2 separate discords for max and classic... and the steam forums still exist as well.
Even when this forum was active, the main channel browsed was "product chat"... the other channels were unfortunately neglected.
