Hi there,

1) I would like to modify the option "Share with". I want to keep only the option Everyone. I know I can make an hack css but I would like to remove definitively the others option. How can I do that ?

Placed attached file on path below:
template\current_template\html\com_easysocial\privacy\default.privacy.options.php

Secondly, I would like the Share social option was included as shown on the screenshot attached
