How can I exempt individuals words from auto-linking to a Glossary entry?

If you don't want particular word to be linked in glossary(e.g. in a Forum post) then:

1. In edit mode, locate and click the Toggle HTML Source button on the formatting toolbar (appear as '<>' symbol).
2. Locate the piece of text you want to exempt from autolinking.
3. Before and after the text respectively, add <nolink> and </nolink>.
4. Save the changes.
