Glossary helps newbies understand the jargon which always crops up when specialists talk about a topic. Doctors discuss CBC and EKG and CCs. Web developers keep talking about CSS, P2P, XSLT, etc. This is all intimidating for newbies. The Glossary module scans posts for glossary terms (and their synonyms) in the body. If found, the glossary indicator is inserted after the term, or the term is turned into an indicator link depending on the settings. By hovering over the indicator, users may learn the definition of that term. Clicking leads the user to that term presented within the whole glossary.
