There is a lot going on in the new Templates. If you would like to spend a couple of hours going over some of the finer points, plan to attend one of the scheduled Template training sessions ITG is offering.
http://itgtraining.unl.edu/ gets you to the latest in HTML, Dreamweaver, CSS and, yes, Templates training. The Templates training is provided free. If you would like to brush up on your technique here and there, consider looking over the online training provided: http://www.unl.edu/webtraining/
