How Can You Tell If Someone On Facebook Has Opened A Message You Sent Them?
2010-02-06 at 03:46 pm hugegeOn Facebook, is there a way you can tell if someone has opened a message you sent them (if you send them an email through Facebook’s messenging system)? If so, how can you tell?

You can’t, its a privacy thing -_-
you probably getting, ignored just like i do.
thats what good about myspace is you know when someone has read it and bebo when you know if they have been online.
normally if someone is on one they might be on the other.
i don’t think you can!!!
