You can make the most of this hour if you have some text that needs to be indented or centered to be presentable.
Any type of outline, bullet points from a presentation, numbered steps, glossary, or list of textual information from a database will serve as good material with which to work.
If the text you'll be using is from a word processor or database program, be sure to save it to a new file in plain text or ASCII format. You can then add the appropriate HTML tags to format it as you go through this hour.
