JFBCComments in content

Few answers, none that are a perfect solution for what you're looking for.
1) A long time ago, Facebook actually allowed guest comments. They removed that feature about a year ago, and we don't understand why. We're doing a big investigation (see below) into the FB Comments and are definitely going to see if there's some way to re-enable guest comments that hopefully they've just hidden (and not disabled permanently). No guarantees though.
2) Due to user feedback, we've working on a lot of improvements to the JFBCComments functionality. One of these is easier administration of comments (so you know what's been posted, where, and when), more easily. The other is ways to integrate we want are for posts (from FB) to post into 3rd party components. That way, someone can post in either the FB box or jcomments and they'd both go to jcomments (but FB comments would get posted to FB). This 2nd part is still under investigation, so no guarantees of it happening, but we'd love to make it easy if possible.

Again, the above doesn't provide you any solutions now, but we'd love your feedback on whether you think either of the above would work for you or if you have other ideas.

Yes, the loadmodule tag is how we'd recommend including the comments if you want it to display in a specific spot on your page.

Thanks for the feedback on the option you prefer. The posting to 3rd party components won't be in the 3.2 release, but we do plan on improving the comments features a bit in that release. After that, we'll be working on more improvements for better integration with the next few releases.
