Bad news about that.

Good point. I don’t think I’ve used :( myself either. I stand corrected.

Only :) or :( are is considered acceptable. And only in an informal context with work colleagues, never with anyone more than 1 step removed from you (meaning it might be ok with your supervisor if that’s the kind of relationship you have, but never with your boss’ boss). I don’t make the social rules, don’t @ me.
