Thanks for the great tutorial! There was about 5 minutes around the grep explanation where you were typing off the screen, but not a huge deal.

GREP don't work! have you ever thought of reviewing what you've done or do you just stick it up on the site. you cannot see what the grep is typing! i also dont understand why you display variable with their parents its not necessary and confusing. for a professional work other people who are much stupider then you have done a better job.
