UBB.threads PHP Forum Software Community Forums Resources and Customizing How Do I? Last Post Column

I have a couple of restricted forums and a couple of archive forums. How do I set the "Last Post" column so that a topic doesn't show up for those particular forums?

I think that you can only do this if the forums are set as Teaser forums.

Then go to CP > Display Options > General > Primary tab > Forum Summary Options and remove the check from 'Show latest post in teaser forum'.
