The Search area of the site lets you enter search terms, as well as search any one or multiple portions of the site for those key words, including user blogs, the information area of the site (FAQs, etc, referred to as book in the Search page), comments, polls, news stories and user profiles.
On the main page of the site there is also a Calendar box to browse the story items chronologically.
Also on the main page, every news story has a category or categories; clicking a category name shows recent stories only in that category.
A new interface for searching by a combination of date and category will be added in the near future.
