struggling with webCT

I'm testing all the components of the new webCT

1. the calendar tool does not automatically put an event for when problem-sets are due instead the calendar event is listed as when the problem-set starts. I posted a request for help to Ask Dr C, webCT's help board
2. the discussion boards were very cumbersome to setup for each recitation, hence I reverted to one discussion board per problem set
3. I was not able to find a way for the students to document they have done the pre-lab. To make sure these are not dropped from student's radar screens, I'm making them as compulsory as the labs to pass the course
