Just to clarify, when you enable Facebook Friend Connect on your blog, for people to use it, do they also need to set-up a Disqus comments account?

I followed the instructions and successfully installed it on my blog (hosted on Squarespace). When I tried to post using FB FC, it bizarrely returns a 'null' value for my id, and it can't access my FB avatar, but it does provide a link to my FB profile. However, it also directed me to set-up a Disqus comments profile. I'm assuming that this behaviour isn't what is supposed to happen, but I'm struggling to fix it.

This is partly because I've subsequently linked my FB profile to my Disqus comments profile, and then it simply uses the avatar/ profile info for my Disqus profile, when I signed in via the FB connect button. That's fine - however, Disqus still doesn't seem to be able to post comments to my FB news stream.

There doesn't seem to be a way at the Disqus end, to 'unlink' my Facebook profile from my Disqus comments account (even if I toggle the post comments to FB setting on/off), so now I'm not sure how to test whether FB Connect is working on my site for new visitors - who don't have a Disqus profile.

Any help much appreciated!

I imported the wrong files into my songbird database - now there's lots of duplicates. How do i clear the database and rebuild it, without deleting the media files themselves?

The scores for my posts are different on my website (using the aiderss widget) from the scores given to my posts in google reader. Why is that?
