Roleplaying is not speaking ancient english (or any other language). Answering to the OP I would define roleplaying as "reacting to the game according to a character's role". According to that definition, roleplaying is not either overacting in a tavern, but rather reacting to the situations created by the game mechanics in character. In other words, the game sets you a conflict of any kind and you react as your character is supposed to do.

There may be a contextual problem when it is the game itself who creates OOC circumstances, which is what happens when you find a bug (broken quests for instance). In such cases, by common sense, one cannot enforce any roleplaying rule because it is not possible to react in character to a game bug, is it?

If there is a channel for such cases, then it is recommended to use it.
