This vassalage stuff is very interesting, and I have tried to understand all that you have said, but I must ask you to summarize, and address my question.

I am assuming that vassalage gets you money.
Once you have gotten them to accept becomming you vassal, do you then state the money you want? Or as I believe makes more sence, you ask for the money when you are requesting them to become your vassal. Yes?
Can you later change the amount they tribute?
Do you state both the amount and the number of turns they must pay?
and the number of turns they must remain a vassal?

My ignorance is always overcome by asking many stupid questions...when theyare answered, intelligently.

Regards, Greg.

PS An unrelated question: Can you tell me how to track amy answers I might receive from my posts? I seem to find it impossible to go back to the forum / thread and check whether someone has answered my querry/posts.
