Low level dungeon finder

Hey, I remember in other servers I played, you could queue in dungeon finder even for lower level dungeon (grey), but in my case it only shows the green and above ones (suited for my level). Is there a way to join dungeon finder for lower areas or do I have to manually set up a group or go solo?

Thanks!

Bump, I'm curious.

Bump 2 - I am really curious too. I only have the Lich King ones available.

rdf tool can only be used to que for dungeons around your level. to go into low level ones you have to walk there and enter manually.
