Isn't it about time we had cross-world Tell? So when you want to mention something to someone you just saw in an instance, for example. Now that we have Cross-World visit, seems a small matter to have cross-world tell. Maybe not "Chat", but Tell sure would be nice. Just to say thanks or something to someone you just saw.

Ah, come on, we can do this. Put one of your interns on it for a summer project.
