@Draug- There is a reason I put "required?" in parentheses, because you are right, of course, that in non-anon games especially reviewing game history is considered standard (although I can say that I have never done so). Nevertheless, let me try to clarify what I was trying to say. On webdip, maybe the fact x is a frequent 1904 stabber is something that I can (ought to?) use to my advantage. On the other hand, the expectation is that in-game play is only affected by diplomacy-related reasons. I don't read the forums that often, but I think that you are fond of saying something to the effect of "I won't back down from anyone in the forums even if that makes them not like me, but that doesn't mean I am volatile (or whatever) when I'm playing." And that is a perfectly valid thing for you to say; the forums aren't supposed to affect the games.
That isn't how F2F works, at least in my experience. For example, in F2F, my favorite two people to ally with are the two people who are most competitive with each other in real life, as they are then always trying to one up each other and will ultimately make a mistake. And that (or something like it) is how you are supposed to play F2F. In webdip, (again, in my opinion, and I may be somewhat biased since I don't think people have particularly strong opinions about me) the "ethic" dictates that any read like that be made in-game.
I'm not sure if I am communicating well, as it is really late, but that is my attempt.
