You'll have to do some testing, but I think you can do what you're looking for. Basically, each Feed post gets a URL like:
www.facebook.com/SourceCoast/posts/841713419194409
So, we just need to get the page name and ID of the specific post and build the URL accordingly. To get the right info, edit the /components/com_jfbconnect/libraries/provider/facebook/channel/page.php file. Around line 42, you'll see:
$post = new JFBConnectPost();
Add the following line after that:
Then, in the facebook.php template file you edited above, you can add a link to the post like:
<a href="https://www.facebook.com/SourceCoast/posts/<?php echo $this->id; ?>">Link to post</a>
Obviously, change SourceCoast to your Page Name.
There is a way to dynamically get the Page Name so it's not hard-coded as well, but for now, test that. The above has *not* been tested by us, but we definitely like the idea and will probably implement it in an upcoming release. Your feedback beforehand would be great!
Thanks,
