Settings?

i'm thinking about using the Privateer Press Iron Kingdoms setting as a part of my upcoming campaign. What are the rules about using somehting like that on the forums?

I know I can't use any of thier imagry and names but I really just want to use the world and setting. The PC's won't need any of the stats

Not a problem as far as I'm aware.
It should be no more illegal to use than Forgotten realms.
