Thank you for your answers, guys!
Another noob quiestion, if you don't mind: I upgraded my Civ4Col version with patch 1.01f and now I don't understand how can I start war with my European rivals? I've already played more than 60 turns, I established diplomatic relations whith two neighbouring European nations, and I still don't see any option to start war with them neither in Diplomacy screen (I don't see option "Get ready to WAR" or something") nor in any other way.
What is wrong with me?
