I have a bad cold and won't be teaching today.
Please continue with the Tutorials. I uploaded Tutorial #2 in the post below. One thing I would add is that if you're having problems selecting particular blocks or surfaces, try maximizing the window you're working in. Also make use of the 3D view to confirm which block or surface is selected. You can also change how the blocks in each window are rendered by right clicking and chaning the rendering style. Changing from wire frame to solid rendering may help.
Sarah Garmisa informs me that apart from 2 machines with faulty monitors, all machines have a functioning Windows installation. Please contact her directly in the user support office if you have any problems.
I'll be checking email this afternoon so email me if you have any questions.
