Comments Plus - FB comments not showing up...

Very simple question - I activated the plugin and the tabbed comment box appeared as expected. If I make a comment using WP - it works. If I make a comment using FB, it seems like it's working, but the comment doesn't show up - not sure if it's actually being published or what the problem is.

Let me know if you have any ideas..

Update: It was my fault - I just had to approve the comments.... I believe that the same way I was confused though, other people might be as well... since we are used to fb comments getting auto-published through the other FB plugins, so I thought I should keep this live anyway.

On a sidenote: What do you guys do with comments? Do you use Akismet and auto-approve everything, or do you moderate them?
