Printable pages.
With some help from the instructions at CogDogBlog, I have created a secondary stylesheet that is used when someone attempts to print this page. It removes the left and right columns and removes display-specific formatting. Best of all, this took maybe ten minutes. I will likely continue to muck with it, but it fills a need. (Selecting "Print Preview" from the File menu on this page will show you what it looks like.)
