Okay sorry to do this, but I think a forum would be better than google wave. I say this because its easier for people to sign up and join and its easier to show threads to non members.
Please take a minute to check out

This will not change, so don't worry. Sorry about the confusion.
I put up a mini practice script (pretty simple) Under Assignments/Week One. You can see the instructions on top and then see posts below. Feel free to comment on people's scripts (I put a simple script up to show you). If you need help, go to the help section.
