This change will be included in the next release. Nobita Social Groups, or any other add-on or custom code, can add autolink integration by extending the vw_AutoLink_Model class via the proxy system in vw_Hard_Core::resolve_class_name (see /vault/core/model/vw.php).
vw_AutoLink_Model::detect_by_forum($parser, $forum) can be used to detect the forum data and determine if relevant to your add-on. If a match is detected, return a unique identifier used to enable/disable autolinks in your add-on; otherwise return the parent. If you have more specific filtering, like a custom autolink setting in your add-on's nodes, you can check for it here.
vw_AutoLink_Model::more_checkboxes() can be used to add your add-on's unique identifier (mentioned above) to the list of available options on the settings page where auto-links are normally enabled/disabled.
Add a phrase for the unique identifier, with phrase name settings_vw_autolinks_option_UNIQUE = checkbox-label-text
The class is fully commented with explanations how to extend it properly.
