The heart of the Knowledge Center software is the "Knowledge Navigation Console". The console window allows users to access postings and a visual display of the ratings that other people have given the posting. Ratings and comments are submitted by clicking on the feedback and submission area just below the posting. Further below the main window, a scrollable lists of comments provides for unlimited feedback on each posting. The comments are divided into three categories: supporting comments, opposing comments and misc.comments. In version 2.0 of the software, each list of comments is automatically sorted by its own agreement level rating, allowing the strongest arguments on both sides of any issue to appear right below the posting itself. This has the added benefit of minimizing redundant comments. Instant email links below each comment facilitates communication and the creation of loyal online communities.
