Make that two who are interested.
I spent a straight whole four hours in there with a PUG recently: it ended incomplete after a great deal of pain and two cracks at the Lieutenant. I'd join any BG run chiefly to clear him and his related deed (though armor barter tokens are a big bonus, especially the one for helms!).
9 pm to midnight on weeknights is a safe bet for my usual playtimes. I'm on GMT+8.
