_ This file is a copy of the 1.8 version of this file. I copied the 1.8 version of the file because I am making changes in the description of external links. Before this date, the Groups chapter held work that I did in early 2011. I was not able to complete that work and probably will not be able to complete the work any time soon. See the file called 09_GroupsAndLinks.html/UG/09_Groups.html for the work I did in early 2011.
