Add-on Programming posts

I wonder if is possible to program a post to be published in certain data, like we can do in facebook pages.

My community has a xen forum and a facebook page so would be very useful to program a post the same day that I program the facebook post sending facebook people to that post. For that, would be very useful also to know the post's link address just you have programmed it to insert it in the programmed facebook message.

Thanks a lot!
