If you are not on the list posted outside SF 2302, there are two possibilities. You may have enrolled in the course some time last week, in which case your account wasn't created with the original batch. I expect to hear about the new batch, which should include you, today. I'll post the revised list. If you enrolled before last week, then something is wrong. It's probably just that you accidentally enrolled in 148 in the wrong term. Check your enrollment through your Registrar.
