https://gfy.com/showthread.php?t=1083653 I made a thread about it.
Like someone posted your suggestion would be bad for forum traffic (separate off topic forum). My suggestion was have it all in this forum but make people choose prefix (biz or OT) when posting the thread. And then everybody could filter this forum by choosing to see only biz threads. Its a WIN WIN suggestion, there is no drawbacks, but looks like nobody cares...
