forum display - sort open threads by date then show closed threads?

[waitstate]

we are looking into getting VBulletin and wonder if we will need a hack to have the forum display show only the open threads first (sorted by most recent day) then show the closed threads or if there is a built in capability in VBulletin.

Right now the forum display seems to sort by date only. We want something like this:

Open Thread - 30 Jun 02
Open Thread2 - 29 Jun 02
Open Thread3 - 25 Jun 02
Closed Thread
Closed Thread2
Closed Thread3

Thanks in advance for any info you can give me. We just are worried how much stuff we are gonna have to hack to bring this thing up once we get it...
