reason why i mention the knight thing.. is.. well.. i was thinking new estates might well mean more attachment to a particular region.
it could well go like this. you list out all the characters, sort of like now.. and then opens up new page for a detailed history of each character - detailed as in knight of X, lord of Y, duke of Z, etc... skip things like change class..
i suppose, it all depends on who's doing the reading. a player might well fancy reading up what he did 1/2 year ago, but don't fancy jotting things down in wiki. so detailed stuff could well be useful for him.
