I've heard from a few of you about problems accessing the Blackboard site for the course. It seems that only students from Lecture 1 were automatically enrolled. I've asked to have everyone from Lecture 2 added, and I'm told that should happen by the end of the day today. Don't worry, though, as there is really nothing on the Blackboard site yet, other than a link to the 21-260 Web Site.
UPDATE: It appears that all enrolled students have now been added to the Blackboard site. If you are still having problems accessing the site, let me know.
