I have used the '<!--nextpage-->' tag to split my page into 5 pages.
I am using a bookmarking plugin (http://codecanyon.net/item/wordpress-user-bookmarks-standalone-version/6584179)
where by a user of my site can bookmark a certain page of the website so it may be easier for them to find later or keep it for future reference.
The problem occurs that if they want to bookmark http://domain.com/examplepage/4/
the first page gets bookmarked which is http://domain.com/examplepage/
The plugin uses post->ID to bookmark a page.
Is there way to get the post->ID or make a post->ID for the nextpage tag.
