I know Instant Messages are a popular feature of Facebook, but I’d like to use FB without letting anybody know I’m online. 90% of the time I get IMs, they are from very chatty, pesky people I knew from high school whom I don’t have the heart to de-friend outright, but I would rather deal with in something other than real time, like e-mail or wall posts. (Part of this is the 13-hour time difference between Korea and the US East coast; their lunch break is when I’m trying to check my messages before I go to sleep.)
Is there a way to disable this feature? I can’t find it under “Privacy Settings.”
