If I get you right, you dy try to talk say make our moderator create another sub board wey go specialized on trading discussion.
In my own honest view, you get a very good point here no  doubt, but na the activeness be the issue.
As it stands now, we get three board wey be our main discussion board, politics and society and off topic board, honestly speaking na only the our main discussion board dy mostly active, most of the thread for politics & society and off topic na our moderator move them go there because na there him see them Dem fit to be, people no dy like post there because them dy mostly feel say merit source dy hardly check post their unlike the main board wey be the center of attention, so I believe say even though them create another board wey be trading discussion board, people go still carry trading post put for our main board because them want where the post go get more visibility.
