Hello!  Just got the game and it is a LOT of fun, but here is a simple question that has been bothering me.  If I want to talk with the AI civs, all I can do is trade with them.  Is this right?  Seems like i should be able to tell them that I don't appreciate their starbase location or their ship buildup.  Or to leave a friend alone, etc...  Is this not available or am I just too dense to find the option?
Thanks!!
