Help with wordpress plugin - publish_future_post() action

Hi All

Just wondering if anyone has any experience of using this hook, I am using the wpvb-threads plugin that uses the vbulletin data manager to auto post to a vbulletin forum.

It works fine unless the post is scheduled, in which case it is not added to the forum

I have found an action publish_future_post() but can't find any documentation for it at all

Tried adding

add_action('publish_future_post', 'wpvbt_exec');

PHP:

to the action hooks of the plugin but it is not posting. I don't really know what data it is carrying or under what variable names to be able to get it to work.

Anyone any ideas.

Thanks
