How to: All sub forums their threads show in the main forum?

[Flying Girl]

Hello every body,

I have sub forums. I want to let their threads show in the main forum that they are sub in it. How?.

For example:

General Forum

sub forums: People, Education, Entertainments


When you open it. You will see upper the sub forums

People

Education

Entertainment


Then you will see the General Forum with its threads.


I want let these sub-forums ( people, education, entertainment ) show their threads in the General Forum. and no body can add new thread directly from general forum no. They must choose the best sub-forum then click add thread then they add what they want. Then this thread will show in that sub-forum and also show in the general forum.

Please, help.

This for example:
http://montada.com/forumdisplay.php?f=66

But it is an Arabian forum. You can know what I mean by it.

Thanks.
