Easiest Suggestion ever: Could you please add an emoticon that means "Acknowledged"? Sometimes, when I'm part of a group, I just want to acknowledge having read a message. I don't specifically want to like it. In fact, sometimes it's awkward to like the message, (i.e. "I'm feeling sick", I'll be away from Skype for a couple of hours", etc.) I just want a more "businessy" way of acknowledging that I got the message without putting a smile on it.
