Does what it says, except for the search functionality doesn't pull in results if you search for the name or username, even when copying and pasting the username or name. Can't figure that out.

But it's a good start to build on if you want to modify it to suit your purposes.

Community builder is a necessary feature of any joomla site trying to have a community (not just content driven) feeling. I needed to create a daily coaching media component for our website and ol' faithful Community Builder allowed me to gather the required information about the user (which I needed to determine gender and their fitness level) by just adding fields to the profile. I also found the plethora of plugins tailored to work with community builder like Mamblog and CB Profile Gallery to be just what I needed. They all integrate into the person's profile, so it feels like a cohesive unit. This is more than a component, it is like myspace within joomla because it has so many plugins available for it
