Posts to descend in one forum?

[adrianne]

I know how to make it so posts are descending in all the forums but is there a way to make it so posts (not threads) only descend in only one particaular forum? Basically, I would like the posts in one particular forum to read from newest to oldest.

Write a plugin to change the option $vbulletin->userinfo['threadedmode']==3 (newest first in linear mode) when a user is in that forum?

Thanks....I'm not sure how to do that though.
