Display Facebook User on Posts at Facebook

Hey there,

i've just purchased the Ultimate Facebook plugin, works fine!
Here's how I use it:
I give users the ability to submit posts from the frontend of my site. They could login via your Plugin. When they submit a post it's also automaticly published on the belonging Facebookpage. It would nice if not the page is the author (inside Facebook) but the Facebook User who submitted the post.

If this won't work, is there an option how I could style the Facebookpost a bit. Because for now there is no featured image, simple the site title an one sentence of the content.

Thank you in advance
