Picht,
No, and we wouldn't recommend posting the whole article to Facebook at all anyways. Facebook uses Open Graph Tags to show snippets of your content in a user's feed. JFBConnect fully supports Open Graph Tags to try to automatically set the best snippet for you.
Users, most likely, don't want a whole article in their feed as it's not conventional.
I hope that helps explain. If you really want to post the full article, I'd love to hear more about why, though I don't think we'd be able to help you implement what you're looking for in JFBConnect.
Thanks,
Alex
