Removing 'search our community' in Scholar theme - part two

Hi:

the production site I'm working on is here:
http://few.modernmediajapan.com/

I found this topic before, and tried doing what was suggested, and only succeeded in erasing the whole sidebar. The top was from two years ago, so I assume that sidebar.php has changed considerably since then. So, how do I remove the 'Search our community' widget at the top of the homepage sidebar. I want the sidebar to remain widgetized, keeping the Upcoming Events, Strategic Partner, and any other widgets I need to put there, but I want to remove 'Search our community'.

thanks,
Terri
