I want the posts in each forum to list in order of "latest replied to". That is, the latest-replied post should be at the top of the forum, and others ordered accordingly.

There doesn't seem to be any way to do this! 

I have tried 

Topic Manager Options | Date For Ordering | Created

Topic Manager Options | Date For Ordering | Modified  


Neither of those work... NEED some kind of order by "Latest reply" option urgently.

also there seems to be some kind of bug in the Article Order option list ( see screencap)
