Enrolled in an online UofT course, but where is everything?

I've enrolled in MGY277H1 on Rosi, but the course hasn't appeared on Blackboard at all yet... I assume that this is where video lectures and/or required readings and assignments and ALL that JAZZ will be, but am I totally wrong? Do online courses take longer to go up on Blackboard? Or is there a secret online location where online courses are held which you only know if you know?

I'm sure some of y'all have done some online classes, so please tell me how to gain access to & succeed in this mysterious world!

Thaaaank you!
