How to Show Multiple Forums

[ShannonA]

Anyone have mods that would allow the simultaneous display of multiple forums?

I'd ideally like something like this:
http://forum.rpg.net/forumdisplay.php?f=3,89

Or:
http://forum.rpg.net/forumdisplay.php?f=3&f=89

So that I could provide a view of the two forums mingled together.

I suppose such a mod would need a way to distinguish which forum you're posting to, for new stuff ...
