Change default sorting method for every forum

[eoh]

Hi,

I have a forum with several subforums. How do I change the default sorting for threads for each forum ?

I've found several pieces of code for changing it for all, but not for seperate forums.

For instance :

Forum a : default sorting by last posted message
Forum b : default sorting by thread title descending
Forum c : default sorting by last posted message

Any help is welcome !
