Hah...You in need of work too, I see. Well, I'm not sure about the whole walkthrough thing. I think that is more frustrating than anything else to walk someone else through something. But that is just me.
Sounds like you are doing that whole achievement thing though. I'm not much of one for that, as anyone looking at my constantly shifting score due to some issues with LIVE where I keep losing points and things. Don't mind though, it isn't a big thing for myself.
