The problem is from your site loading so many jquery libs.
Now please complete some tag as following
1) Your site must to load one jquery file and need disable jquery file of other extentions, please see my snapshot
2) The script tag of jquery need put below the script tag of mootools
3) You need use the jquery No Conflict Function: http://api.jquery.com/jQuery.noConflict/
you can put the code at end of this file /components/com_community/assets/joms.jquery.js
[PHP]
jQuery.noConflict();
[/PHP]
