I plan on using trackbacks to link to other blogs automatically and help generate traffic to the site.  I also have other friends who love to blog, so trackbacks will be a good tool for referring traffic in between the blogs.

What I actually found out is that on the auto discovery "tries" to work, but I think the url that it's sending out is slightly different from the actual url containing the special trackback code, therefore when the other blog looks for for the information, it never finds it.  When referring either the permanent link or the trackback url, when I link from another blog, it never adds the trackback comment. The fustrating thing is that it doesn't log any information on failures either, which makes it hard for those of us who don't know how to program in asp.net yet (Cold Fusion Programmer).

I had finally gotten frustrated and moved over to community server to handle my blogging since it handles that and the forums pretty well.  I'm still looking into a way to get the dotnetnuke's trackback working properly, but it isn't as high of a priority as it was before. .
