Is it possible to add GNU Social to the shares available? Unfortunately, I'm not sure how the transform bit works.

'gnusocial' => array(
		'url' => '~URL~/notice/new?content=~TITLE~ ~LINK~',
		'transform' => array(
			'link' => array(),
			'title' => array(),
		),
		'help' => 'https://gnu.io/social/',
		'form' => 'advanced',
	),

The result, for instance, should be like https://herds.eu/notice/new?content=%23FreshRSS+is+amazing%20https%3A%2F%2Ffreshrss.org

Thank you. :)
