You'll need a password to log in. Initially your login and password are the same, your acpub userid. So, you might login for the first time by specifying ola and ola as both login and password (if your acpub login is ola, that is).
You should change your password as soon as you login if you want some degree of privacy. Use the Student Tools link/then Change your Information. (Student Tools is where you see grades too.)
You can log in as user guest with password guest, but then you won't see grades.
After spring break news will migrate to the CourseInfo discussion board.
