Easily create an exit meta tag redirect page to warn users they are leaving your website and automatically redirect them after a set time period.
You can set the wait time to 0 seconds, but by doing that people probably will not see your exit warning or advertisement.
If you know CSS the text the shortcode outputs is inside a div with the class wpexitcode. You should be able to style the div and text how you want.
No, this plugin makes it possible to redirect from the page/post you create in WordPress.
