This definitely isn’t done perfectly, but I just hacked Yelp into this plugin in about 15 minutes. The steps:
1) Using the plugin editor at http://www.yoursite.com/wp-admin/plugin-editor.php edit the file social-media-feather/synved-social/synved-social.php. Alternatively you could edit this file some other way.
Add the following lines below the linkedin section:
‘yelp’ => array(
‘link’ => ‘http://www.yelp.com/biz/yelpid’,
‘title’ => __(‘Find us on Yelp’),
),
2) Go to your plugin settings to configure your correct URL for Yelp at http://www.yoursite.com/wp-admin/options-general.php?page=synved_social_settings
3) Find your favorite Yelp icon such as this one: http://westwoodva.com/wp-content/uploads/2013/06/yelp.png
Resize it to 96×96 and upload it to the wp-content/plugins/social-media-feather/synved-social/image/social/regular/96×96 directory.
That is all I needed to do. Your mileage may vary due to different site setups. And these changes will likely be erased when you update this plugin. But hopefully this will get some folks started.
