Select “Knowledgebase” from the Support Module. While FAQ’s usually provide short and concise answers for customer questions, the Knowledgebase is oriented toward detailed and in-depth discussion of various issues.
When selecting individual items in the list of Knowledgebase articles, an icon indicates whether an entry is an individual article or a folder of articles. Folders lead to additional lists of articles, which fall under the same subject. To view a specific Knowledgebase article (or to open a folder), click on the corresponding Title.
