The Muddiest Point - Week 1

I'd like to stray just a little to gripe about the fact that I'm still not on CourseWeb. I registered the week before the semester began (seemingly late, but still cool with LIS I guess) and have yet to receive the letter - through the olde thyme mail - that has my user name and password. This is the procedure right? I phoned and was instructed to wait for the letter ... My question to anyone that knows anything about security is this: why? Am I just being cranky for being a week behind?
