Forum Facebook integration
1. At the end of a blog post, instead of usual comments section would instead be a forum thread, that links to the site's traditional forum. So if you wanted to comment, you would have to login to the forum and contribute.
2. If you contributed to the forum discussion, it would be posted to your Facebook news feed.
I thought Tal.ki would do this but you can't keep all your forum threads in a classic forum like this one.
