Hmmm... using Blogger's backlinks was not as easy or as good as I had hoped. The links were not added retrospectively, and it seems hugely difficult, even for a hacker like me, to get the correct number of backlinks to occur in the footers on the main page.
I've opted to go back to TrackBacks for the post footers, but still keep backlinks enabled for those who can't or don't want to use TrackBacks.
Best of both worlds? We'll see... I don't have any more time to waste on it right now.
