Joomla! Community forums make use of a 5 Star Ranking system for users.Rankings are mainly for fun, but may also serve as a pointer for those asking questions when they are able to see the ranking of a user answering their question.When a Joomla! Newbie can see their question being followed to the door by a Joomla! Hero, they probably already felt the special and friendly community spirit that will make them stick around and “pay it forward” by answering other newbies questions. And before they know it, they become a Joomla! Hero too.
