This forum topic is to discuss all aspects of the ShareBox extension.
In particular, if you would like to provide configurations for sharing to services not yet present in the extension, you may add in the following format :
'facebook' => array(
'url' => 'https://www.facebook.com/share.php?u={url}&t={title}',
'title' => 'Share this on Facebook',
'name' => 'Facebook'
)
and I will include it a next version of the extension. Thanks !
