This might be a really stupid question.
The instructions sent to us said "login," but I'm not sure if we need to create the account by scratch. It said we're supposed to use student number and @ and then the school domain.
So yeah, am I supposed to create the account myself? Just making sure since I'm really paranoid and new to this stuff.
