The Specialty Guides Module allows for the "expansion" of any Portal Directory Topic page so that it may include more finely tuned classifications and in-depth details about the Topic. The Dining Guide, linked below, is a great example of how a Specialty Guide can work. Compare the Dining Guide to the regular Portal Directory Topic page titled "Food and Beverage" to see the difference in the detail that's possible through use of the Specialty Guides Module.
