I can translate it, when I am at home later.
About the topic: I think the border between IC and OOC is obvious. IC is EVERYTHING that happens in game, but stuff that's written in (( )) and of course additional the RP-forum-stuff as well. Every interaction is or at least should be based on your char's experiences and as independent from your OOC-opinion as possible. I say "as possible", because I am aware that nobody can completely turn off their brain and that you can never fully ignore your personal OOC-background. But every char should be able to play with every other char (even if they despise each other IC and only fight), no matter how things are between the players OOC, and every player should be able to talk to everybody OOCly, no matter what happend IC.
Again, it's not always possible to not have your OOC-self influence your characters behavior.
In the end, I am a big fan of "What happens IC stays IC". And I will actually name an example here, while Kat and Erin broke up IC and she won't take him back, no matter what, I am still in contact with PO Erin from time to time and there are absolutely 0 hard feelings OOCly.
And as a small addition: I have played the game ever since I was 12ish, I think. And I admit that it was difficult for me to not mix IC and OOC in the very beginning, likely even until I grew up to, like, 16 or 17. Today I am absolutely aware of the differences between me and my chars. They aren't me, I am not them. While we may share some opinions or traits, they are mostly independent from me and I let them make choices I would very much dislike OOCly, if that fits their character.
