Change sort mode in forum

Hi,

I just investigated about Kunena forum (powering this Fourm).
Default sort of posts (for guest or new users) is a missing parameter that will come in V2.0 (current is V1.7).
There's a hack about some $default_sort config parameter, but it does not seem to work (I changed it without much effect).


So only registered users can select their sort option.
You found the good parameter.
