Facebook comments & Kunena

The primary integration of JFBConnect with Kunena is the profile import which gets a user's name, profile information, and avatar into Kunena in just a few clicks and without any forms. It's a simple matter to add the Comment (or Like) button to every post in Kunena by using either the JFBCComments (or JFBCLike) module and assigning them to your Kunena menu item. We also support 'tags' that you can put in your template, like:
{JFBCLike} and {JFBCComments}

However, what I think what you're asking is a little different than just adding a comment box. I think you want to post to a user's wall when the create a new topic or response within Kunena. Currently, this isn't available, but in a future release, we're planning to add a simple javascript line you could add to any Submit (or Reply) button that would pop-up a window to also post into the user's wall.

No, JFBConnect does not do any sort of cross-posting. The Facebook Comments box is threaded, but we don't insert those comments into other extensions, they are only displayed in the Comments module.

Hope this all makes sense and helps!

Ah.. sorry for the lengthy explanation then. We try to make sure the right expectations are met, so never try to beat around the bush on what we do.

As to your question, yes, our comments module uses the 'new' comment code. We actually have the ability to use the old xid parameter, in case you have some pages with comments you wanted to preserve, but by default all new comment boxes automatically use the href from the URL of the page they're shown on. You can hard-code this URL to specific pages (to show the same comment box across multiple pages) and our JFBCContent plugin will automatically set the proper canonical URL when Likes or Comments are shown in articles. That way, if the article is in a blog view, the Like buttons will all be for each article shown, not for the blog-view page itself.

Hope that makes sense, and should you need anything else, just let us know!
