Thank you for your review and vote on our website (as you said, you didn't review the extension in here).
We're a bit surprised by your review and wonder if you are viewing our new website, which is completely redone since begin of this year, or another website: just in case:
Website of Community Builder: http://www.joomlapolis.com/
Regarding uninstalling CB: Uninstalling Community Builder is just a matter of uninstalling the component and the modules you installed. Nothing more required, as CB and CB Team plugins are cleanly implemented, not modifying any joomla tables nor any joomla files or directories. So here again we wonder if you are reviewing CB or something else.
You are really welcome to post to our forums on joomlapolis.com suggestions for improvements in our website in case something wasn't clear for you. It will be much more useful than here.
However, all I was looking for was a modul where I can put my Adsense Code, chose the position I would like it to be placed on the site, safe it and done. And finaly it looks like I found exactly that.
