Well, over meebo, right? It's not that I dislike VMs, it's just that it's hugely inconvenient due to it being a form of 'pseudo-instamessaging', for lack of a better term. I'll tutor for HG/SS, I'm foggy with DP/Pt, and from what I hear it's largely easier to do HG/SS as opposed to DP/Pt. As for Emerald, I'm completely in the dark, I might learn in future though.
