diplomacy with more than 7 rival civs

[takamine]

how do you view more than the first 7 rival civs on the foreign advisor's screen when you are playing with a higher number of AI players?

You can't view more, but you can change the one that you view with Shift + Right Click

The best way I've found is if you go to your trade advisor, you'll see a list of all the other civs you've met, broken up into 'Can trade with' and 'Can't trade with'.

Just double click on the name of the civ and it'll bring up the diplomacy window for that civ.
