I'm glad if I can help.
Hopefully someone will eventually help out with your trackback. My commenting helps keep this post on the first page of topics.
Just to make sure you are using trackback correctly, in which case it's a user-error instead of a technical error, make sure you put the trackback URI in the trackback URI spot, which is seen directly under the post body. For example, to trackback to one of my posts, use this one .
Feel free to do this to test.
Pingback, I believe, works more easily, You just link to a permalink in your entry body and make the sure the box marked "PingBack the URIs in this post" is checked.
For pingback to work, the weblog you're pinging obviously has to be set up correctly. Feel free to try to pingback http://www.arghnoname.com/archives/2004/05/20/28/ to test your pingback ability.
Technically I've never been pingbacked or trackbacked, but I assume they're working on my site.
I apologize is this is a little too basic for you. If you get any warnings or other indications that trackback, etc aren't working, you should post that information here.
