So far this module looks like it ticks all the boxes for a knowledgebase/ FAQ, system.
The many categories in categories which can be in many categories is excellently handled and ever part of this extension is integrated almost seamlesly with the admin side of joomla!.

The only slight drawback i have at the moment is i cant seem to change the title which shows on the page for configuration items like "show tags" :( but thats minor considering the huge benefits this extension delivers.
