Thanks for the welcome, Robert!
I disabled comments entirely on my blog because I didn't want to have to deal with the spam problem. But on my new site I'm going to enable them again. I've got a lot of catching up to do on the whole blog thing and I'm not entirely sure I yet understand the trackback deal.
Somebody tell me if I'm wrong here... lets say I blog about what somebody else blogged. I link to that blog in my blog but I then should add a trackback if I want that blogger to know that I blogged about his blog?
Sounds pretty Smurfy to me.
