Just giving you guys a heads up, I'm going through libraries\bookmarks.php for your groups "share this" button in the discussion area. These seem to be the only ones working:

$this->add( 'Facebook' , 'facebook' , ' www.facebook.com/sharer.php?u={uri }' );
$this->add( 'del.icio.us' , 'delicious' , ' delicious.com/save?url={uri }' );
$this->add( 'Digg' , 'digg' , ' digg.com/submit?phase=2&url={uri }' );
$this->add( 'Stumbleupon' , 'stumbleupon' , ' www.stumbleupon.com/submit?url={uri }' );
$this->add( 'Google+' , 'google' , ' plus.google.com/share?url={uri }' );
$this->add( 'Twitter' , 'twitter' , ' twitter.com/home?status={uri }' );
$this->add( 'Blogmarks' , 'blogmarks' , ' blogmarks.net/my/new.php?mini=1&url={uri }' );
$this->add( 'Technorati' , 'technorati' , ' www.technorati.com/faves?add={uri }' );
$this->add( 'LinkedIn' , 'linkedin' , ' www.linkedin.com/shareArticle?mini=true&url={uri }' );
$this->add( 'Newsvine' , 'newsvine' , ' www.newsvine.com/_tools/seed&save?popoff=0&u={uri }' );

I think it would benefit from adding reddit also: $this->add( 'Reddit' , 'reddit' , ' reddit.com/submit?url={uri }' );

Hi Bryan,

Thank you for reporting.. I will add this as a bug..

cheers.
