The URL for Fark in sociable.php does not properly submit links.
To correct the link, look for the "old code" lines, below, in sociable.php, somewhere around line 175, and replace then with the "new code" lines
// old code to be replaced
'Fark' => array(
'favicon' => 'fark.png',
'url' => 'http://cgi.fark.com/cgi/fark/submit.pl?new_url=PERMALINK&headline=TITLE&linktype=Misc'
// To post to a different category, see the drop-down box labeled "Link Type" at
// http://cgi.fark.com/cgi/fark/submit.pl for a complete list
),
//new code; replace code block above with this
'Fark' => array(
'favicon' => 'fark.png',
'url' => 'http://cgi.fark.com/cgi/fark/farkit.pl?h=TITLE&u=PERMALINK'
// To post to a different category, see the drop-down box labeled "Link Type" at
// http://cgi.fark.com/cgi/fark/submit.pl for a complete list
),
Your users still need to log in to Fark to submit by this method but it does work.
