Thank you, yes I am aware, and so I answer only fresh messages that I received from an online sender... but as soon as they go offline, so does the service. They can't read me anymore when I reply them from email. Untill they log back in world... so far, I know of 3 of my friends that have the same issue and not only with messages coming from me... 2 of them are gmail users, I dont know about the 3rd...
