Facebook issues..
 

First of all, this is my first thread and i might have some problems with the writing because the clock is 03:00 in my country

All i want to do, is that when i paste a link of a thread from my forum to facebook, i want to make facebook copy the first words from the thread to the specific facebook post.
I want this, so i can post on my forum`s facebook`s page the most interesting topics.

I know that i must use the facebook app, to make this possible.

So, the short version:
When i paste a link to appear on facebook the same thing that appears when i check the "Post to Facebook" box


Thanks!
