I would guess that English is not borble's first/native language, or that he's dyslexic, so cut him some slack on that. I'm a stickler for spelling and decent grammar myself, but I understand there's a lot of folks with dyslexia or minor learning disorders that make spelling difficult (my mother and sister are like that).
borble: I'll take a look at your class material soon and try to give a thorough analysis of whatever game mechanic problems it has. Probably in a few days, as I've got to prepare a bit for my Thursday/Friday games first.
