we can't help you there. We are only able to give support to our own Cookbook extensions or those we use our self as extensions to the Cookbook on this site. e.g. a translation file for Joom!Fisch for multilingual cookbooks and the WikiBot plugin that we also have made multilingual.
Hopefully someone using Joomsocial can help you.
You can also try to contact the creater of this plugin. You'll find name and homepage in the Help/Faq - extensions.
